I tested with a number of random floating values. In most of the cases, the expanded result is exactly the same as libcall result.

But when `fmod(a,b)` is very close to `b` (smaller than `1e-10`, for example, `fmod(521862.045173469, 31.048432006988875)`), the result would be totally wrong..  I'm thinking about a solution.
