Diophantine Approximation on Quadratic Polynomials
Given an integer $a$ which is not a perfect square, I'd like to ask how to perform Diophantine Approximation of $frac{x^2}{y^2}$ to $a$ where $x$ and $y$ are integers. Specifically, integers satisfying $|frac{x^2}{y^2}-a|<epsilon$ are preferred.

Set $y$ to a power of $10$.

Just find a rational approximation $frac{x}{y}$ (for example with the continued fraction method) of $sqrt{a}$. This gives a reasonable approximation of the desired form.
