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 (<syntaxhighlight lang=apl inline><</source>), 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:

<syntaxhighlight lang=apl inline>≥</source> <syntaxhighlight lang=apl inline>0</source> <syntaxhighlight lang=apl inline>1</source>
<syntaxhighlight lang=apl inline>0</source> <syntaxhighlight lang=apl inline>1</source> <syntaxhighlight lang=apl inline>0</source>
<syntaxhighlight lang=apl inline>1</source> <syntaxhighlight lang=apl inline>1</source> <syntaxhighlight lang=apl inline>1</source>

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