In this case, the input data word, IR 010, contains #0014, and f(0014) = #0726
is output to R, IR 011.
5-24 Floating-point Math Instructions
The Floating-point Math Instructions convert data and perform floating-point
arithmetic operations. CQM1H-series CPUs support the following instructions.
Data Format 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.
Real number = (–1)

s: Sign
e: Exponent
f: Mantissa
