Calcula a e (número de Euler, 2.7182818) elevado à arg poder dado, menos 1. Esta função é mais preciso do que a expressão std::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 std::exp(arg)-1 if arg is close to zero.
