Main article: Comparison function

Greater than or Equal to () is a comparison function which tests whether the left argument is tolerantly greater than or equal to the right argument, returning 1 if this is the case and 0 otherwise. It is the negation of Less than (<), and in fact was called Not less in APL\360.

Boolean function

When the arguments to Greater than or Equal to are Boolean, it is the converse implication Boolean function:

0 1
0 1 0
1 1 1

In the context of logic, it can be read as is implied by.
