Stacks

The unit employs memory blocks, called stacks, for storage of low priority values and commands. There is a 10-level numeric value stack, a 26-level command stack, and a 10-level program subroutine stack. If you execute a formula so complex it exceeds the amount of stack space available, an error message appears on the display (Stk

ERROR during calculations or Ne ERROR during execution of a program subroutine).

P.22

• Calculations are performed according to the priority sequence. Once a calculation is executed, it is cleared from the stack.

• Storing a complex number takes up two numeric value stack levels.

• Storing a two-byte function takes up two command stack levels.

k

Input, Output and Operation Limitations

The allowable range for both input and output values is 10 digits for the mantissa and

2 digits for the exponent. Internally, however, the unit performs calculations using 15 digits for the mantissa and 2 digits for the exponent.

Overflow and Errors

Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display. Further operation of the calculator is impossible while an error message is displayed. The following events cause an error message to appear on the display.

P.401

P.399

P.50

• When any result, whether intermediate or final, or any value in memory exceeds

±

9.999999999

×

10 99 (Ma ERROR).

• When an attempt is made to perform a function calculation that exceeds the input range (Ma ERROR).

• When an illegal operation is attempted during statistical calculations (Ma ER-

ROR). For example, attempting to obtain 1VAR without data input.

• When the capacity of the numeric value stack or command stack is exceeded (Stk

ERROR). For example, entering 25 successive ( followed by 2 + 3 * 4 w .

• When an attempt is made to perform a calculation using an illegal formula (Syn

ERROR). For example, 5 ** 3 w .

• When you try to perform a calculation that causes memory capacity to be exceeded

(Mem ERROR).

• When you use a command that requires an argument, without providing a valid argument (Arg ERROR).

• When an attempt is made to use an illegal dimension during matrix calculations

(Dim ERROR).

• Other errors can occur during program execution. Most of the calculator’s keys are inoperative while an error message is displayed. You can resume operation using one of the two following procedures.

• Press the A key to clear the error and return to normal operation.

• Press d

or e

to display the error.

k

Memory Capacity

Each time you press a key, either one byte or two bytes is used. Some of the functions that require one byte are: b , c , d , sin, cos, tan, log, In, , and

π

. Some of the functions that take up two bytes are

d

/

dx

(, Mat, Xmin, If, For, Return, DrawGraph,

SortA(, PxIOn, Sum, and

a n

+1

.

When the number of bytes remaining drops to five or below, the cursor automatically changes from “ _ ” to “ v

”. If you still need to input more, you should divide your calculation into two or more parts.

• As you input numeric values or commands, they appear flush left on the display. Calculation results, on the other hand, are displayed flush right.

Graphic Display and Text Display

The unit uses both a graphic display and a text display. The graphic display is used for graphics, while the text display is used for calculations and instructions. The contents of each type of display are stored in independent memory areas.

Variables

This calculator comes with 28 variables as standard. You can use variables to store values to be used inside of calculations. Variables are identified by single-letter names, which are made up of the 26 letters of the alphabet, plus

r

and

θ

. The maximum size of values that you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent. Variable contents are retained even when you switch power off.
