Description
The input comparison instruction compares the data specified in S
1
and S
2
as
single-precision floating point values (32-bit IEEE754 data) and creates an
ON execution condition when the comparison condition is true. When the data
is stored in words, S
1
and S
2
specify the first of two words containing the 32-
bit data. It is also possible to input the floating-point data as an 8-digit hexa-
decimal constant.
