[New-bugs-announce] [issue29956] math.exp documentation is misleading

[Alexander Belopolsky]

New submission from Alexander Belopolsky:

The math.exp(x) function is documented to "Return e**x" <https://docs.python.org/3/library/math.html#math.exp>.  This is misleading because even in the simplest case, math.exp(x) is not the same as math.e ** x:

>>> import math
>>> math.exp(2) - math.e ** 2
8.881784197001252e-16

I suggest using e<sup>x instead of e**x to distinguish between Python syntax and mathematical operation and change "Return e**x" to "Return e<sup>x, the base-e exponential of x."
