Compare Less Than or Equal
The Compare Less Than or Equal function compares
IN1 less than or equal to IN2 with the Boolean result
placed in OUT. The input and output data types can vary,
but they must be of the same type.
Byte comparisons are unsigned. Integer, double integer,
and real comparisons are signed.
