Type in a 5 to replace the 6. One caution in replacing characters - once you type a new character over an existing character, the original is gone forever! You cannot recall an expression that has been typed over.

Sixty seems Iike a reasonable number of groups, so you decide that each small group will consist of five participants. Recall is also useful to verify your last entry, especially when you results do not seem to make sense.

For instance, suppose you had performed this calculation: Input Display. Even a tired, overworked manager like you realizes that 6 does not seem to be a reasonable result when you are dealing with hundreds of people! Recall you entry using the [E]. To correct this entry you wish to insert an added zero. Using the [E], move the cursor until it is positioned over the zero.

When making an INSert, you position the flashing cursor over the character before which you wish to make the insertion. Input Display 1. Pressing INSert moves all the characters one space to the right, and inserts a bracketed open slot. The flashing cursor is now positioned over this open space, indicating the location of the next typed input. Type in your zero. Once the entry is corrected, display your new result. On the other hand, suppose that you had entered this calculation: Input Display.

The results seem much too large. If you only have people attending the meeting, how could you have "small groups"? Recall your entry using the CE. To correct this entry eliminate one of the zeros. Using the CE move the cursor to the first zero or any zero. When deleting a character, you position the cursor "on top of" the character to be deleted. Pressing DELete causes all the characters to shift one space to the left. It deletes the character it is "on top of" and the space the character occupies.

The flashing cursor stays in the same position indicating the next location for input. Since you have no other changes to make, complete the calculation. Note: Pressing the SPaCe key, when it is positioned over a character, replaces the character leaving a blank space. DE Lete eliminates the character and the space it occupied. And no wonder, you have too many operators! To correct this error use the DELete key. Part of your responsibility in planning this conference is to draw up a detailed budget for approval.

Figure your total budget: Input Display. What is the swards budget? In serial calculations the entry must begin with an operator. The 0 should be used as a character only and the keys is inoperative. Continue allocating your budget. Negative Numbers Since you want the awards dinner to be really special, you decide to stay with the planned agenda and spend the additional money.

However, you wonder what percentage of the total budget will be used up by this item. First, change the sign of the remaining sum: Input Display. Diving by gives you the percentage of the total budget this new figure represents: Input [2] Display. Compound Calculations and Parentheses In performing the above calculations, operations into one step. For instance, on one line: you could have combined several of these you might have typed both these operations.

If you are unfamiliar with the concept of variables, they are more fully explained in Chapter 4. Now that you have planned your awards dinner, you need to complete arrangements for your conference. You wish to allocate the rest of your budget by percentages also.

First you must find out how much money is still available. You can display the current value of any variable by entering the alphabetic character it is stored under: Display. You can then perform calculations using your variable.

The value of R will not. These are certain limitations on the assignment of variables, and certain programming procedures which cause them to be changed. See Chapter 4 for a discussion of assignment. See Chapter 5 for a discussion of the use of variables in programming.

You must separate the equations with commas. Only the result of the final calculation is displayed. Scientific Notation People who need to deal with very large and very small numbers often use a special format called exponential or scientific notation.

In scientific notation a number is broken down into two parts. The first part consists of a regular decimal number between 1 and The second part represents how large or small the number is in powers of As you know, the first number to the left of the decimal point in a regular decimal number shows the number of Ts.

Scientific notation breaks down a decimal number into two parts: one shows what the numbers are, the second other shows how far a number is to the left, or right, of the decimal point.

For example: becomes 1. You can see that it would take a lot of writing to show 1. But, in scientific notation this number looks like this:. This computer uses the capital letter E to mean "times ten to the":. E Those of you who are unfamiliar with this type of notation should take some time to put in a few very large and very small numbers to note how they are displayed. In other words the largest number is:.

Those with some can be represented in 16 binary bits. The circumstances in which this form is used are noted in the Chapter 8. Last Answer Feature In the case of the serial calculation, you could use the result of the calculation only as the first member of the subsequent calculation formula. Refer to the following example. If you operated these keys just after completing the calculation example above, you should see " The numeric data displayed is the result of the your last calculation.

In the case of the serial calculation described above, you could use the result of the previous calculation only as the first member of the subsequent calculation formula.

With the last answer feature, however, you can place the result of the previous calculation in any position of the subsequent calculation. As shown in this example, the last answer can be recalled anytime and anyplace, but will be replaced with a new last answer resulting from the last calculation.

The last answer cannot be recalled; when the computer is not in the RUN mode, program execution is temporarily halted, or the Trace mode is selected. Length of Formula The length of a formula you can put into your computer has a certain limitation. If you attempt the 80th key stroke, the cursor will start blinking on that character, indicating that the 80th key entry is not valid.

These functions will be described as follows: Functions Trigonometic functions sin cos tan Inverse trigonometric functions sin"! Some other functions may also be entered with alphabetic keys. For examples, "sin 30" may be entered either by operating [! For trigonometric and inverse trigonometric functions and coordinate conversion, the desired angular unit must be specified in advance.

These instructions are used to specify angular units in program. For practice, use these instructions to specify angular units in the following calculation examples: 0.

For coordinate conversion, the conversion result is transferred to variables Z and V. Therefore, the previous contents of Z and V will be cleared. Direct Calculation Feature I n the manual calculation described up to now, we always used the I ENTER key to terminate a formula and obtain the calculation result of the formula. It should be noted, however, that this "direct" calculation mode is not available for functions requiring entry of more than one numeric value binominal functions such as power, power root, or coordinate conversion.

The direct calculation feature is not effective for formulas: e. The direct calculation feature is effective only for numeric values. Therefore, if hex numbers A to F are entered for hex to decimal conversion, the direct calculation feature will remain inoperative. Priority in Manual Calculation In the BASIC mode, you can type in formulas in the exact order in which they are written, including parentheses or functions. The order of priority in calculation and treatment of intermediate results will be taken care of by the computer itself.

The internal order of priority 1 2 3 4 in manual calculation is as follows: Recalling variables or 1T. Function sin, cos, etc. These letters, numbers, and special symbols are called characters. In order for the PC to tell the difference between a string and other parts of a program, such as verbs or variable names, you must enclose the characters of the string in quotation marks ". Hexadecimal Numbers The decimal system is only one of many different systems to represent numbers.

Another which has become quite important when using computers is the hexadecimal system. The hexadecimal system is based on 16 instead of These correspond to 10, 11, 12, 13, 14, and Those with some computer background may notice that the last number is the same as the largest number in the special group of limits discussed in the paragraph "Limits" on page Each byte can be thought of as a single character. For instance, the word byte requires four bytes of memory because there are four characters in it.

The number displayed is the number of bytes ava ilable for writing programs. Th is technique works fine for words, but is very inefficient when you try to store numbers.

For this reason, numbers are stored in a coded fashion. Thanks to this coding technique, your computer can store large numbers in only eight bytes. This gives you quite a range to choose from. However, if the result of a calculation exceeds this range, the computer will let you know by turning on the error annunciator and by displaying the error message in the screen. For the error message refer to the Appendix A. But how do you go about storing all this information? It's really very easy.

The computer likes to use names for different pieces of data. Let's store the number into the computer. You may call this number by any name that you wish, but for this exercise, let's use the letter R. The statement, LET, can be used to instruct the computer to assign a value to a variable name but only in a program statement. However, the LET command is not necessary, so we will not use it very often. The computer now has the value associated with the letter R.

These letters that are used to store information are called variables. The computer responds by showing you the value on the right of your screen. This ability can become very useful when you are writing programs and formulas. Next, let's use the R variable in a simple formula. In this formula, the variable R stands for the radius of a circle whose area we want to find. Th is technique of using variables in equations will become more understandable as we get into writing programs.

So far, we've only discussed numeric variables. What about storing alphabetic characters? The screen shows BYTE. This time the display is on the left side of the screen, instead of the right. Character array variables. Fixed Variables The first section, fixed variable, is always used by the computer for storing data. It can be thought of as pre-allocated variable space.

In other words, no matter how much memory your program uses up, you will always have at least 26 variables to choose from to store data in. Fixed memory location are eight bytes long and can be used for only one type of data at a time.

To illustrate this, type in the following example: A. This confuses the computer so it says that there is an error condition. Simple Variables Simple variable names are specified by two or more alpha-numeric characters, such as AA or B 1.

Unlike fixed variables, simple variables have no dedicated storage area irt the memory. The area for simple variables is automatically set aside within the program and data area whena simple variable is first used. While alphanumeric characters are usable for simple variable names, the first character of a variable name must always be an alphabetic character. If more than two characters are used to define a variable name, only the first two characters are meaningful.

Each simple character variable can hold up to 16 characters. Array Variables For some purposes it is useful a list of scores or a tax table. An array like a list, or two-dimensional, like a table. To define an array, the DIM short for dimension statement is used. Arrays must always be "declared" defined before they are used. Not like the single-value variables we have been using. The form for the numeric DIMension statement is: D 1M numeric-variable-name where: numeric-variable-name is a variable name which conforms numeric variable names previously discussed.

Note that when you specify a number for the size you get one more location than you specified. Examples of legal numeric DIMension statements are:. The second statecreates an array AA with 25 locations. The third statement creates an array one location and is actually rather silly since for numbers at least , it is the as declaring a single-value numeric variable.

The first X denotes a series of numeric storage locations, and the second a single and different location. Now that you know how to create arrays, you might be wondering how it is that we refer to each storage location. Since the entire group has only one name, the way in which we refer to a single location called an "element" is to follow the group name with a number is parentheses. This number is called a "subscript". Thus, for example, to store the number 8 into the fifth element of our array X declared previously we would write: X 4.

If the use of 4 is puzzling, remember that the numbering of elements begins at zero and continues through the size number declared in the DIM statement. The real power of arrays lies in the ability to use an expression or a variable name as a subscript. To declare a character array a slightly different form of the DIM statement is used: DIM character-variable-name where: character-variable-name is a variable name which conforms normal character variables as discussed previously.

Note that when you specify a number, you get one more location than you specified. If used, it specifieds the length of each of the strings that comprise the array.

Length is a number in the range 1 to Libble takes abuse of its services very seriously. We're committed to dealing with such abuse according to the laws in your country of residence. When you submit a report, we'll investigate it and take the appropriate action. We'll get back to you only if we require additional details or have more information to share. For example, Anti-Semitic content, racist content, or material that could result in a violent physical act. For example, a credit card number, a personal identification number, or an unlisted home address.

These are the standard Amphenol connectors commonly used for RS serial communications. Sharp produced a number of programmable desktop calculators in the early s prior to the handheld devices.

These machines were programmed by hand, with some having a magnetic card system which could store programs and data. The Cartridge Calculator Series introduced in was the first programmable product in which the program could be permanently stored on ROM chips. The program was written in a micro-code similar to the code used in the early desktop calculators and the first programmable handheld calculator.
