Re: sqrtint for rationals
Speaking of which, I _think_ I might have a solution for the Table-
Specifically, if one has available integers of any length already ie
thru' GMP, then why can't one just use _perfectly correct_ rationals
(described as two integers, top and bottom of a fraction) [a little
bit akin to two-coordinate complex numbers].
I don't see why then one couldn't carry through rationals w/ perfect
accuracy thru all operations... or is this already what is used in
