Hi, there is a method RR(x).nearby_rational(...) which returns a rational number .... it would be convenient for me to have a method which returns a rational number which has also a rational square root, something like RR(x).nearby_rational_perfect_square(...) , I'm not asking for a workaround, at least not for the most obvious one (taking the square root of x and using .nearby_rational with adjusted tolerance...), may this method could be useful for others, too .... Thanks, Georg
