While I like them a lot, it's time for them to go:
1. It's hard to remember which one does what
2. They've failed to catch on
3. No operator overloading for them
4. They are only rarely needed; a special operator is not justified
(per our discussion)
5. a peephole optimization can detect isnan(a) || a < b and have it
translate into one instruction, same as a !>= b, thus addressing the
efficiency problem that the FP operators were meant to solve.
Peephole optimizations have a precedent:
c = a / b;
d = a % b;
only use one division-and-remainder instruction.
