P99_ABS #define P99_ABS (   EXPR )    (P99_SIGNED(EXPR) ? p00_abs_signed(EXPR) : P99_C(uintmax_t, EXPR)) Compute the absolute value of an integral expression. Returns The return type of this macro is uintmax_t. It must be so, since if we have a two's complement representation the value -INTMAX_MIN is not representable in intmax_t. EXPR is guaranteed to be evaluated exactly once. This macro is preferable to the C99 function imaxabs. That function forcibly returns a value of type intmax_t, and might thus fail for INTMAX_MIN.
