Compute the absolute value of an integral expression, using integers with extended width.
- Returns
- The return type of this macro is p99x_uintmax. It must be so, since if we have a two's complement representation the minimum signed value of p99x_intmax is not representable in p99x_intmax.
EXPR is guaranteed to be evaluated exactly once.
