# Exponential (Arg) - 1 (G Dataflow)

Version:

Computes 1 less than the value of e raised to a specified power (x).

When x is very small, this node is more accurate than using Exponential then subtracting 1 from the output.

## x

An input to this operation.

This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.

## exp(x) - 1

Result of the operation.

This output assumes the same numeric representation as x. When x is of the form x = a + bi, that is, when x is complex, the following equation defines exp(x) - 1:
$\mathrm{exp}\left(x\right)-1=\left(\mathrm{exp}\left(a\right)×\left(\mathrm{cos}\left(b\right)+i\mathrm{sin}\left(b\right)\right)\right)-1$
