ENH: Make numpy floating scalars consistent with Python divmod.
The following numpy scalar floating functions are reimplemented
using the npy_divmod function.
- remainder ('%')
- floor_division ('//')
- divmod
Note that numpy scalars warn on zero division rather than raise.
divmod example, Python floats
In [1]: a = 78 * 6e-8
In [2]: b = 6e-8
In [3]: divmod(a, b)
Out[3]: (77.0, 5.999999999999965e-08)
Before this commit numpy float64 gave
In [4]: divmod(float64(a), float64(b))
Out[4]: (78.0, 0.0)
After this commit numpy float64 gives
In [4]: divmod(float64(a), float64(b))
Out[4]: (77.0, 5.9999999999999651e-08)
