I know, but there's no arithmetic, only value copying. I'm not sure,
but I think that such operations shouldn't change the value of floats.
Otherwise it would mean that the bits get corrupted when they are
loaded/saved from memory, which would be catastrophic for computing ;)
But maybe comparison of floats is performed in some strange way by the
processor. I haven't checked that on such a low level so I'm not 100%
certain.
Anyway, using delta shouldn't affect performance significantly and I
agree that it's safer, so no problem. That's why I sent two patches.
