9.6.3 Greater than
The Greater than function compares two numerical input values and
outputs a "1" at its Boolean output if value x
1
is greater than x
2
,
otherwise a "0".
In view of the fact that numerical values are presented on computers
as floating point numbers with finite precision, it is difficult to make
decisions in border ranges. (See the explanation in Chapter 9.6.1,
Equals
function). This is however usually irrelevant in everyday
usage, because the accuracy is to 8 significant decimal places.
When however it is important that a precise decision be made for a
border range, then you can install the Rounding function upstream
(see Chap. 9.3.8).

9.6.4 Greater than or Equal to
The Greater than or equal to function compares two numerical input
values and outputs a "1" at its Boolean output if value x
1
is greater
than or equal to x
