NAME
       abs - return absolute value of an argument

SYNOPSIS
       abs(x);

ARGUMENTS
       x
           the value. If it is unsigned type, it is converted to signed type first. char is
           treated as if it was signed (regardless of whether it really is) but the macro's
           return type is preserved as char.

RETURN
       an absolute value of x.
