Calculation apparatus and storage medium in which calculation program is stored
摘要：
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.
摘要（中）：

在图形计算器中，十进制计算单元获得由输入装置输入到第n位和第（n + m）个数字的算术表达式的计算结果。 当（n + m） - 数位计算结果中从最高有效位到第（n + 1）位数值为零时，相对于加法或减法，CPU将修正n位数计算结果 加或减为零。
