| Jan 18 at 2:38 | comment | added | qwr | Related projecteuler.net/problem=804 Endagorion has a method that works for any shape with overlapping x ranges in O(circumference) by stepping through x ranges for each y. | |

| Jan 18 at 0:26 | comment | added | qwr | For the Gauss circle problem, the number of interior and boundary points can be computed with Jacobi's two square theorem and the factorization of the radius length. | |
| Jan 18 at 0:24 | comment | added | qwr | I think it's more interesting to have separate questions for interior points and boundary points, as boundary points is a Pythagorean triple like \$(bx)^2 + (ay)^2 = (ab)^2\$. | |
| Jan 18 at 0:23 | comment | added | vengy | I don't think there's a closed form, I got the idea from the Gauss Circle Problem which there's no formula to find the number of lattice points and involves some enumeration. | |
| Jan 18 at 0:19 | comment | added | qwr | Is there a closed form? | |
