Re: [sympy] What is the Sympy function for $\nu_2(n)$ the 2-adic valuation of $n$?

This is the closest thing. It is only in the development version of SymPy, but 1.10 will be released with it soon. https://docs.sympy.org/dev/modules/polys/numberfields.html#p-adic-valuation Depending on what you want to do you can easily define your own by subclassing Function and defining the ap

Hi, googling turns up nothing. Was wondering if Sympy has a v_2(n) function such that it's part of the expression tree and so Sympy knows about rules such as v_2's complete additivity, i.e. v_2(xy) = v_2(x) + v_2(y) and so on and can thus simplify expressions involving it if possible. Thanks!

Do you maybe have smart quotes around the m in the symbols arg? /c On Friday, February 11, 2022 at 4:14:31 PM UTC-6 thomas...@gmail.com wrote: > I have a test program: > > from sympy import symbols, Rational > m = symbols('m') > temp = Rational(0) > temp = temp.subs(m, m) > temp = 0 > temp = tem
