The Floating-point Math Instructions convert data and perform floating-point
arithmetic operations. CQM1H-series CPUs support the following instructions.

Floating-point data expresses real numbers using a sign, exponent, and man-
tissa. When data is expressed in floating-point format, the following formula
applies.
s e–127
Real number = (–1) 2
s: Sign
e: Exponent
f: Mantissa
