How can the square root of a u128 be calculated? The resulting number can be a u128 after some rounding. f64 has a f64::sqrt function, but I dont think we should be converting u128 to f64.

Below I have adapted code from William Kahan and K.C. Ng (look at the comment block on the bottom) written in 1986 to produce an approximation of 1 / sqrt(x) where x is an IEEE-754 double precision fl...

I am trying to propagate uncertainty in Python by adding two columns together of a Pandas data frame and then taking the square root. However, when I try to use Python's math.sqrt function, I receive ...
