* GH-102341: Improve the test function for pow (#102342)Partha P. Mukherjee2023-03-051-6/+5
| | | Co-authored-by: Terry Jan Reedy <tjreedy@udel.edu>
* bpo-46218: Change long_pow() to sliding window algorithm (GH-30319)Tim Peters2022-01-021-0/+22
| | | | | | | | | | | * bpo-46218: Change long_pow() to sliding window algorithm The primary motivation is to eliminate long_pow's reliance on that the number of bits in a long "digit" is a multiple of 5. Now it no longer cares how many bits are in a digit. But the sliding window approach also allows cutting the precomputed table of small powers in half, which reduces initialization overhead enough that the approach pays off for smaller exponents too. Depending on exponent bit patterns, a sliding window may also be able to save some bigint multiplies (sometimes when at least 5 consecutive exponent bits are 0, regardless of their starting bit position modulo 5). Note: boosting the window width to 6 didn't work well overall. It give marginal speed improvements for huge exponents, but the increased overhead (the small-power table needs twice as many entries) made it a loss for smaller exponents.

* Issue #21741: Update 147 test modules to use test discovery.Zachary Ware2015-04-131-4/+1
| | | | | | | I have compared output between pre- and post-patch runs of these tests to make sure there's nothing missing and nothing broken, on both Windows and Linux. The only differences I found were actually tests that were previously *not* run.

This is what 754-inspired stds require, as the "true result" is an infinity obtained from finite operands, i.e. it's a singularity. Also changed float pow to not be so timid about using its square-and-multiply algorithm. Note that what math.pow does is unrelated to what builtin pow does, and will still vary by platform.
