Les coupures de branche sont le long de l'axe réel négatif. `sqrt` calcule la racine carrée de l'ordre de la demi-plan droit. Si `x` est un nombre réel négatif, la valeur de retour va se coucher sur l'axe imaginaire positive .
Original:
The branch cuts are along the negative real axis. `sqrt` computes the square root in the range of the right half-plane. If `x` is a negative real number, the return value will lie on the positive imaginary axis.
