[QUOTE="Dik T. Winter, post: 2463273"] Well, assuming those are ints: unsigned int abs(int n) { unsigned int x = n; unsigned int m; m = (1 << (sizeof(int) - 1)) & x; m = (m - (m >> 31)) | m; return (x ^ m) + (1 & m); } Where is the comparison? But, whatever, abs is standard already in C89, and I have no idea how it is implemented... But of course, there is the probability of overflow lurking in that formula. [/QUOTE]
