Floating-point Math Instructions Section 3-15
Inputting the Instructions
The input comparison instructions are treated just like the LD, AND, and OR
instructions to control the execution of subsequent instructions.
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
1
+1, S
1
and C2=S
2
+1, S
2
.)
Input type Operation
LD The instruction can be connected directly to the left bus bar.
AND The instruction cannot be connected directly to the left bus bar.
OR The instruction can be connected directly to the left bus bar.
Symbol Option (data format)
= (Equal)
< > (Not equal)
< (Less than)
<= (Less than or equal)
> (Greater than)
>= (Greater than or equal)
F: Single-precision floating-point data
