Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only) Section 3-16
3-16 Double-precision Floating-point Instructions (CS1-H, CJ1-
H, CJ1M, or CS1D Only)
The Double-precision Floating-point Instructions convert data and perform
floating-point arithmetic operations on double-precision floating-point data.
The CS1-H/CJ1-H CPU Units support the following 20 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
2
e–1,023
(1.f)
s: Sign
e: Exponent
f: Mantissa
The floating-point data format conforms to the IEEE754 standards. Data is
expressed in 32 bits, as follows:
