> and `log` base `math.e` is likely to be less accurate than plain natural log Nope, that's nonsense, since the two-argument form simply divides by log(base), and while log(math.e) is mathematically not exactly 1 (its exact value, assuming IEEE 754 binary64, starts 0.9999999999999999468176229339410862948..., which is off from 1.0 by around 0.48 ulps), it's *just* close enough that with a well-behaved libm log implementation it's exactly 1.0 after rounding. I still don't like the idea of math.e as a default value here, but I'd have to work harder to identify why it makes me uneasy. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45218> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
