I found sorting large arrays by a comparator that looks at the floating-point difference problematic, especially -ffast-math, (http://stackoverflow.com/questions/24442725/is-floating-point-addition-commutative-in-c.) This is intended to compare 32-bit floats exactly using integer arithmetic. Most...
