Abstract
In a graphing calculator, a decimal calculation unit obtains a calculation result of an arithmetic expression input by an input device to an n-th digit and an (n+m)-th digit. When the values from the most significant digit to an (n+1)-th digit in the (n+m)-digit calculation result are zero, with respect to an addition or subtraction, the CPU corrects an n-digit calculation result of the addition or subtraction to zero.
