≤

Less than or Equal to (≤
) is a comparison function which tests whether the left argument is tolerantly less 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 greater in APL\360.
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 implication, also known as the IMPLY gate:
≤ |

In the context of logic, it can be read as implies.
