Calcula a e (número de Euler, 2.7182818) elevado à arg poder dado, menos 1. Esta função é mais preciso do que a expressão exp(arg)-1 se arg está perto de zero.

Original:

Computes the e (Euler's number, 2.7182818) raised to the given power arg, minus 1. This function is more accurate than the expression exp(arg)-1 if arg is close to zero.
