# exp

This block is part of the [`math`](https://docs.rual.nl/block-types/math) group and was last modified in core [`v13.0.7`](https://docs.rual.nl/core-versions/130007).

Returns the value of E raised to the power of a number

- number_0 required `number`

- Number `number`

A typical wiring for [Exp](https://docs.rual.nl/block-types/math/number_math_exp): the `number` out pin feeds [cast to value](https://docs.rual.nl/block-types/type%20casting/number_convert_to_value).
