Comments? One option would be to define a separate division operator that always returns an integral value and that is truncated toward 0 and use that for the mod function. People might find this operator useful in itself. Another option would be for mod to check if the remainder doesn't have the same sign as the divisor and if so keeping adding the divisor to it until it does. ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
