 inf and nan only exist in Python the
language (including builtins) via casting strings to floats (there are
no arithmetic operations that produce them). 

>>> import sys; sys.version
'3.8.3 (default, May 19 2020, 18:47:26) \n[GCC 7.3.0]'
>>> from math import pi as π
>>> exp = 2**9
>>> a = (22/7) ** exp1
>>> b = π ** exp1
>>> a
4.2679182652117097e+254
>>> a * a
inf
>>> (a*a)/(b*b)
nan

The dead increasingly dominate and strangle both the living and the
not-yet born.  Vampiric capital and undead corporate persons abuse
the lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
