Compare Greater Than
The Compare Greater Than function compares IN1
greater than 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. Time operations are
signed integers.
