Computes 1 less than the value of e raised to the x power.
When x is very small, this function is more accurate than using the Exponential function then subtracting 1 from the output. The connector pane displays the default data types for this polymorphic function.

Inputs/Outputs
x
—
x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.
exp(x) -1
—
exp(x)-1 is of 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 |
