# Exp

> **Note:** **What is it about?**
>
> This page describes the **Exp node** of the Redshift renderer in **Cinema 4D**. It raises e to the power of its input — producing exponential growth curves for falloffs and physically inspired responses.

Returns the exponential of *Input*, using the following formula: e^ *Input*

> **Note:** This is the inverse function of Ln.
