[docs] [issue29956] math.exp documentation is misleading

Serhiy Storchaka added the comment: Nuances of expm1(), log1p(), log2() and log10() aren't beginner topics, but they are documented. I think it wouldn't harm if add "This is usually more accurate than ``e ** x`` or ``pow(e, x)``." The only issue is how to distinguish ``math`` constant ``e`` from mathematical constant *e*. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue29956> _______________________________________
