Return how many Hexagonal Tiling grid points there are inside a circle of radius r centred at (0,0) (including points on the edge). Assume that a Hexagonal Tiling grid is a 2D Regular Hexagonal Tessellation with equal edges of size e=1.
For shifted symmetry purposes, assume that (0,0) is a grid point.
Neither string operations nor interpolations are allowed!
