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:
exp ( x ) 1 = ( exp ( a ) × ( cos ( b ) + i sin ( b ) ) ) 1
