Sommaire

[modifier] Notes

Jusqu'à C99, la direction d'approximation du quotient et le signe du reste dans les opérateurs de division et le reste intégré dans la mise en œuvre a été défini si l'une des opérandes est négatif, mais il était bien définie dans div et ldiv .
Original:
Until C99, the rounding direction of the quotient and the sign of the remainder in the built-in division and remainder operators was implementation-defined if either of the operands was negative, but it was well-defined in div and ldiv.
