Subtraction of Real Number Type Values
In the case of double-length integer type values, an operation using addition and subtraction instruc-
tions (+,
−, ++, --) will be a 32-bit operation. However, when an addition or subtraction instruction is
used in a remainder correction operation (where a multiplication instruction ( ×) is the immediately pre-
ceding instruction and a division instruction ( ÷) is the immediately subsequent instruction), the opera-
tion will be a 64-bit operation.
