Thank you!
Hi Todd,
Yes, ** stands for exponentiation. And exponentiation has higher
precedence than multiplication. See below (I dropped a few zeros to
help clarify):

And what is `2 * 100 ** 2000 `? Is that `(2 x 100)^ 2000`
((2 times 100) to the 2000 power?
Point 1: exponentiation has a higher priority than multiplication.
Point 2:https://rosettacode.org/wiki/Integer_roots
Any chance of you answering the questio

Meaningful digits? Not possible as sqrt uses limited precision. I think
the IEEE 754 doubles that I would suspect to be used internally are

In this instance, I do not care about meaningful. I only
care about the noise. Just has to be repeatable.

Meaningful digits? Not possible as sqrt uses limited precision. I think
the IEEE 754 doubles that I would suspect to be used internally are capped
way below 40 significant deci

Perhaps it is just the mathematician in me speaking, but I think that a
sqrt op might be superfluous and could be replaced with exp as sqrt(x)
== exp(x,0.5). I cannot say anything about numerical stability of
precision, though, so feel free to shoot me down.
