Memory Calculations

This calculator has 6 temporary memories (A-D, X and Y),one independent memory (M) and one last answer memory. Independent memory and temporary memories are only available in the normal mode.

[Temporary memories (A-D, X and Y)]

A stored value can be recalled as a value or variable for the use in equations. In case you store an infinite decimal in the memory, recall it as a variable to obtain accurate answers.

Example:

Memory Calculations

In addition to all the features of temporary memories, a value can be added to or subtracted from an existing memory value.

Last answer memory (ANS)]

The calculation result obtained by pressing = or any other calculation ending instruction is automatically stored in the last answer memory.

Note:

Calculation results from the functions indicated below are automatically stored in memories X or Y. For this reason, when using these functions, be careful with the use of memories X and Y.

• Entry of the multiplication procedure is omitted between ” ” and a variable.

Chain Calculations

This calculator allows the previous calculation result to be used in the following calculation.

The previous calculation result will not be recalled after entering multiple instructions.

Fraction Calculations

• A decimal number, variable, or exponent cannot be entered as a fraction.
• In all cases, a total of up to 10 digits including integer, numerator, denominator and the symbol ( ) can be entered.
• If the number of digits to be displayed is greater than 10, the number is converted to and displayed as a decimal number.

Time, Decimal and Sexagesimal Calculations

Conversion between decimal and sexagesimal numbers can be performed. In addition, the four basic arithmetic operations and memory calculations can be carried out using the sexagesimal system.

Coordinate Conversions

Before performing a calculation, select the angular unit.

The calculation result is automatically stored in memories X and Y.
Value of r or x: X memory
Value of θ or y: Y memory

Modify Function

In this calculator, all calculation results are internally obtained in scientific notation with up to 12 digits for the mantissa. However, since calculation results are displayed in the form designated by the display notation and the number of decimal places indicated, the internal calculation result may differ from that shown in the display. By using the modify function, the internal value is converted to match that of the display, so that the displayed value can be used without change in subsequent operations.

Statistical Calculations
