The following table summarizes the Boolean operators that are available in the F# language. The only type supported by these operators is the bool type.

Operator

Description

not

Boolean negation

||

Boolean OR

&&

Boolean AND

The Boolean AND and OR operators perform short-circuit evaluation, that is, they evaluate the expression on the right of the operator only when it is necessary to determine the overall result of the expression. The second expression of the && operator is evaluated only if the first expression evaluates to true; the second expression of the || operator is evaluated only if the first expression evaluates to false.
