# Boolean true or false. A Boolean has one of two possible values: `true`; `false`. Boolean (logical) operators (*and*, *or*, *not*) take Boolean inputs and yields a Boolean value. Comparison operators on other types ([numbers](/reference/types/number), [strings](/reference/types/string) yields a Boolean value. The following blocks represent the true and false Boolean values, which can be plugged in anywhere a Boolean value is expected: ```blocks true; false; ``` ### See Also [boolean (blocks)](/blocks/logic/boolean)
