Greater than (>) is a comparison function which tests whether the left argument is tolerantly greater than and not equal to the right argument, returning 1 if this is the case and 0 otherwise. It is the negation of Less than or Equal to (≤).

Boolean function

Main article: Boolean function

When used as a Boolean function (that is, with argument consisting entirely of 0s and 1s), it represents material nonimplication, also known as the NIMPLY gate:

> 0 1
0 0 0
1 1 0

In the context of logic, it can be read as but not.
