FUNCTIONAL DESCRIPTION

Decimal point system

Complete floating decimal point system.

Integral number: 8 digits leading zero suppression. Zero shift.

Symbols:

-: negative number display.

E: error display.

M: memory display.

Error detections

System errors occur when:

1. The integral part of any memory calculation result exceeds 8 digits.

2. The division by zero.

3. The extraction of square root of a negative number.

Rough estimate calculation error

When the integral part of the result of any standard functions, percentage, square, reciprocal, or

power calculations exceed 8 digits.

Error indications

System error

“0” is indicated in the 1-digit position and “E” in the sign-digit position.

Rough estimate calculation error

The high-order 8-digit calculation result is indicated together with ”E”.

The decimal point is indicated in the position corresponding to a calculation result of time 10

no zero shift is performed.

Error release

System error

A system error can be released by the ON/C or ON/CE key.

Rough estimate calculation error

A rough estimate calculation error can be released by the ON/C, ON/CE, CE key.

A calculation result is not cleared by ON/CE, CE key but is retained.

Number entry

Numerical can be entered up to 8 digits. Numerical entries equal to 9 digits or more are ignored.

Memory protection

In any error detection, the memory contents is retained.

Memory indication

If the memory content is not zero, “M” is indicated in the sign-digit position.

Doublers key depression

The order of the priority when two keys are being depressed simultaneously, is as follows:
