What could be causing the difference between c++ and python output?

Question

Python

I decided to rewrite a fairly simple program in c++ and ran into the problem that the calculations with a large error differ from the true ones. In python, the result is more accurate, what is the mb related to?

Answer 1

At least the f functions are different for you. In c++ you take the root of the whole expression, but in python you take the root of that part only (1 + x**2)
