Hi.
The fmod() function is not absolutely accurate.
For example:
fmod (1000001, 1000000) --> 9.536743e-01
fmod (1000001, 10) --> 1.015625e+00
The reason is too simple algorithm with float point
arithmetic usage.
fmod() is an important function. It is used in
trigonometric: sin/cos/tan .
After replacement of algorithm (to integral division)
the fmod() became absolutely exact. Speed is up
considarable. Size is increased a little (but the stack
usage is reduced).
Testing in progress...
Fantastic!
I'd rather take an accurate function over a slight increase in size any day.
