* BLD: add back stdlib.h include in pcg64.hChristoph Reiter2022-09-111-1/+4
| | | | | | | | | This seems to have been removed by accident in #21887 stdlib.h is required for _rotr64() further down. Fixes: error: call to undeclared function '_rotr64'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

| | | | | | | | | | | | | | | | | | | | | remove numpy.random.gen, BRNG.generator, pcg*, rand, randn remove use_mask and Lemire's method, fix benchmarks for PCG removal convert brng to bitgen (in C) and bit_generator (in python) convert base R{NG,andom.*} to BitGenerator, fix last commit randint -> integers, remove rand, randn, random_integers RandomGenerator -> Generator, more "basic RNG" -> BitGenerator random_sample -> random, jump -> jumped, resync with randomgen Remove derived code from entropy Port over changes accepted in upstream to protect log(0.0) where relevant fix doctests for jumped, better document choice Remove Python 2.7 shims Use NPY_INLINE to simplify Fix performance.py to work Renam directory brng to bit_generators Fix examples wiht new directory structure Clarify relationship to historical RandomState Remove references to .generator Rename xoshiro256/512starstar
* MAINT: Remove Cython conditionalsKevin Sheppard2019-05-202-2/+51
| | | | Remove Cython conditional compilation and use preprocessor only
* BENCH: convert bencmarks to asv formatmattip2019-05-207-0/+2532
remove files that were part of the origal repo rework randomgen docs to integrate with numpy and fix some links remove convenience functions, require explicit call to gen.brng move code out of numpy.random.randomgen into numpy.random
