計算機。 In a small electronic calculator capable of exponential calculations,
It has a binary operation means whose output changes in a binary manner by operating the exponent operation mode key, and when this binary operation means is in one state, it is possible to change the data of the integer part, and when it is in the other state, it is possible to change the data of the integer part. A small electronic calculator characterized in that data in each part can be changed by numerical operation.
