[editar] Notas

Até C99, a direção de arredondamento do quociente eo sinal do restante dos operadores nativos divisão eo restante foi definida pela implementação se um dos operandos foi negativo, mas foi bem definido no div e 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.
