Calcola la e (numero di Eulero, 2.7182818) elevato alla arg di potenza, meno 1. Questa funzione è più preciso l'espressione exp(arg)-1 arg se è vicino a 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.
