# Work with basic data types

All Flux data types are constructed from the following **basic types**:

-   [Boolean](#boolean)
-   [Bytes](#bytes)
-   [Duration](#duration)
-   [Regular expression](#regular-expression)
-   [String](#string)
-   [Time](#time)
-   [Float](#float)
-   [Integer](#integer)
-   [UIntegers](#uintegers)
-   [Null](#null)

### [Boolean](/flux/v0/data-types/basic/bool/)
