[sympy] Where sympy processes not-evaluated powers?

Hello. I'm trying to modify sympy to avoid of hanging, when numer which is gonna to be computed is tu large. I know how to *raise exception*, but In which file should i look for power computing without eval? In *core/numbers.py* there are mothods for evaluation of numbers. But where should I

Hey, thank you. But *flatten* is executed only then, when argument is symbol, like *2 * x * x* (i.e.). But where is code of numbers eval? sobota, 5 czerwca 2021 o 14:01:46 UTC+2 smi...@gmail.com napisał(a): > processing of args, I believe, is handled in Add.flatten and Mul.flatten > > /c > > On

[sympy] Where can I find code, that evaluates add and multiplication operations?

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

[sympy] Limit max value of computed exception

Hi. I have problem. I'd like to secure of too high computed value to prevent of SymPy Hang. I. E.: latex(expand("2**10**10**10", evaluate=True)) When I execute it by python script it hangs (value is too big). How to prevent of it? Thank You! -- You received this message because you are
