(3) 0~9
a. In setting data in the mantissa section, it is set at the right margin, and the data in more than 11 digits cannot be
input.
b. At the data input against the exponent, the last two numbers are efficients.
(4) • RND
a. The position first pressed has preference, and no input is made to data set in the exponent section.
b. When pressed as the first set number, it is regarded as 0 and • keys are pressed.
c. Random as a 2ndF
Pressing this key shall display the random numbers.
The range of random numbers is 0.000~0.999.
(5) +/-
a. In setting data in the mantissa section, this key reverses the code in the mantissa section.
Similarly, for the exponent section, it reverses the code in the exponent section.
b. For the operation result, this key reverse codes in the mantissa section.
(6) + - x ÷ = ( )
a. When the key operation are performed by these keys according to a numerical expression, a result of the
operation is obtained according to mathematical priorities. Priorities discriminated are:
1) 1 Variable function
2) Expression in ( ); (The most inner expression has priority in case of multiple parentheses)
3) yx, x y
4) x, ÷
5) +, -
b. Whenever the key is operated, the calculator discriminates the above priorities and holds the data and
operation keys pending as required.
This pending action is possible up to 6 times and 7 or more pending become error.
c. ( Key is accepted only immediately after CE, +, -, ×, ÷, y3x , x y , =, ( keys and not accepted in all other cases.
When this key is accepted, the displayed data is cleared to 0.
When ( key is first accepted, the special display “( )” illuminates.
When a parenthesis expression is completed ) and = keys or when it is cleared by the ON/C key, etc, or when
errors are generated, the special display “( )” goes out.
d. If it is within the allowable range of pending, ( can be input into any place in an expression as many times as
desired. However, if the key is pressed continuously 16 times or more, it be comes error.
e. From a viewpoint of numerical expression, even when the corresponding C key is not pressed, the operation is
not executed if the “)” key is pressed. On the other hand, when the “(“ key is pressed and the “=” key is pressed
without pressing the corresponding “)” key, the operation is also completed according to the priority.
