Today I was looking to python docs for doctest and found following
if n+1 == n: # catch a value like 1e300
raise OverflowError("n too large")
Immediately I opened the shell and try it:
>>> from math import exp
>>> n = exp(300)
>>> n
1.9424263952412558e+130
>>> n + 1 == n
True
TIL n+1 == n! and how to guard against a ridiculously large number
