Hi Richard, > Forget that. I'm talking nonsense. No harm, no foul. :-) > An int is signed only if it's smaller than INT_MAX in magnitude. And as long as it doesn't exceed UINT_MAX. Normal promotion rules apply. > Otherwise it's unsigned (hence #defining INT_MIN as (-INT_MAX - 1) On a 2's complement machine. On a 1's complement, #define INT_MIN (-INT_MAX) Sincerely, --Eljay
