Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only) Section 3-16
Options
With the three input types and six symbols, there are 18 different possible
combinations.
Summary of Input Comparison Instructions
The following table shows the function codes, mnemonics, names, and func-
tions of the 18 single-precision floating-point input comparison instructions.
(C1=S
