64-bit and larger integers could be done, but it requires
modification. The integer distributions were written to support C
longs, not anything larger. You could also use .bytes() and
np.fromstring().

What is the use case here? I know of none. Floating point is a bit
weird and will cause you many problems over such an extended range.
