It's supposed to mean that it can be evaluated to a numerical value
with evalf(). I guess infinities are also considered numerical in this
sense.

Why S.Infinity.is_number (as well
as S.ComplexInfinity.is_number) is True and S.NaN.is_number is True,
while sin(S.Infinity) (i.e. AccumBounds) is False?
I just can't understand what is_number means in SymPy.

If you are talking about numerical evaluation, in SymPy, integers wrap
Python integers, so the operations are done in Python itself. Floating
point numbers wrap mpmath, so the code for those will be in the mpmath
library.

Since Python can handle arbitrary precision numbers, doesn't the final
evaluation happen in Python? I have always assumed that to be the case.
E.g. 3*4*x*x is converted into 12*x*x by Python (where x is an instance

The `fu` patterns can be used to do different types of rewriting. But in
the case you gave, rewriting as cos, Pow or Mul might make sense.

Hi.
Where can I find code, that evaluates *Add* and *Mul* operations on real
numbers? I've found the code in *Pow* file (sympy/core/power.py). I know
that there are move files in that dir:
(sympy/core/add.py)
(sympy/core/mul.py)
But I cannot find the line of evaluation.
I.E. where is code tha
