WebAll BitGenerators can produce doubles, uint64s and uint32s via CTypes (PCG64.ctypes) and CFFI (PCG64.cffi). This allows the bit generators to be used in numba. The bit generators can be used in downstream projects via Cython. Generator.integers is now the canonical way to generate integer random numbers from a discrete uniform distribution.
