 ENH: provide a convenience function to replace npy_load_module (#20395) 2021-11-19T14:59:47+00:00 Matti Picus matti.picus@gmail.com 2021-11-19T12:51:36+00:00 58723f3d15f5887c2065b031885fe3d4195ddfd6 `load_module` is deprecated since python 3.4 and will be removed in python 3.12. Use `exec_module` instead. Provide a convenience function in `distutils.misc_utils` instead of `npy_load_module` from `compat.py3k`.

BUG: Get full precision for 32 bit floating point random values. 2021-11-06T07:20:51+00:00 warren warren.weckesser@gmail.com 2021-11-06T06:59:05+00:00 4b9e56921e6343b980b27e308534ca433a4a1fe8 The formula to convert a 32 bit random integer to a random float32, (next_uint32(bitgen_state) >> 9) * (1.0f / 8388608.0f) shifts by one bit too many, resulting in uniform float32 samples always having a 0 in the least significant bit. The formula is corrected to (next_uint32(bitgen_state) >> 8) * (1.0f / 16777216.0f) Occurrences of the incorrect formula in numpy/random/tests/test_direct.py were also corrected. Closes gh-17478. 
The formula to convert a 32 bit random integer to a random float32,

    (next_uint32(bitgen_state) >> 9) * (1.0f / 8388608.0f)

shifts by one bit too many, resulting in uniform float32 samples always
having a 0 in the least significant bit. The formula is corrected to

    (next_uint32(bitgen_state) >> 8) * (1.0f / 16777216.0f)

Occurrences of the incorrect formula in numpy/random/tests/test_direct.py
were also corrected.
