Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only)
Section 3-16
Precautions
The base data (B to B+3) and the exponent data (E to E+3) must be in
IEEE754 floating-point data format.
3-16-21 Double-precision Floating-point Input Instructions
Purpose
These input comparison instructions compare two double-precision floating
point values (64-bit IEEE754 format) and create an ON execution condition
when the comparison condition is true.
These instructions are supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU
Units only.
Note
Refer to
3-7-1 Input Comparison Instructions (300 to 328)
for details on the
signed and unsigned binary input comparison instructions and
3-15-24 Sin-
gle-precision Floating-point Comparison Instructions
for details on single-pre-
cision floating-point input comparison instructions.
