| | * BUG: Get full precision for 32 bit floating point random values.warren2021-11-063-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| |/ | | | | | | | | | | | | | | | | | | There was a mistake in the code that generated the plot in the zipf docstring. The Riemann zeta function is `scipy.special.zeta`, not `scipy.special.zetac`. I also tweaked the sample parameters and the plot code so the plot is a bit more informative.
| * DOC: Fix random.power Raises description (#20205)jessijzhao2021-10-272-2/+2
| | | | | | Current documentation for random.power and random.Generator.power states that ValueError is raised if a < 1; however the power function distribution only supports strictly positive a > 0 and raises ValueError if a <= 0. Fixed documentation to reflect this.
| * DOC: Updated random.uniform docstring parameter description (#20146)Arushi Sharma2021-10-262-3/+8
| | | | | | | | | | | | | | Add note to the description of the \"high\" parameter to indicate that it is possible for the value to be included in the returned values due to floating point precision, despite the fact that it represents an open interval.

| * Allow clib callable build flagsMatthew Brett2021-10-231-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment, we are guessing whether we have the MSVC compiler, by looking at what Python was originally compiled for. That works only if we are using the same compiler, but this is not the case when we compile with e.g. mingw-w64 using Python.org Python. Unfortunately, at the time we are specifying build flags, we don't know what compiler we are using. Allow build flags to clib to be callables that return lists of strings, instead of strings, where the callables can do work like inspecting the compiler, at build time. Use this to check for MSVC at build time, when specifying the `/GL-` flag. See gh-9977 for a related discussion about these flags.

| * MAINT: Avoid use of confusing compat aliases.Antony Lee2021-08-242-2/+2
| | | | | | | | | | | | | | | | | | As of Py3, np.compat.unicode == str, but that's not entirely obvious (it could correspond to some numpy dtype too), so just use plain str. Likewise for np.compat.int. tests are intentionally left unchanged, as they can be considered as implicitly testing the np.compat.py3k interface as well.
