The current evalf() is used to evaluate a numerical expression into a floating-point number using an arbitrary precision library mpmath. What I want to do is to get the best answer for different ranges that varies from (-inf, inf) without increasing precision. for example: expr1 = (x + 1)**0.5

Yes, I just looked closer and what is written there is quite confusing. The purpose of the convention is to define what happens when the upper limit is less than the lower limit. I believe it also defines what happens when the limits are nonintegral, but I could be misremembering that. The

I couldn't find any examples in open issues which require the generating function algorithm to solve. I will keep looking at the issues and the codebase to better understand them. As for the Karr Algorithm, thank you for the suggestion! I will split its implementation to smaller pieces and
