Formula to calculate Euclidean distance or distance between two points: In the above formula, p and q are the two points. I mostly wanted to emphasize how much better the improved formula from Wikipedia is (thanks for the pointer), while being barely more computationally costly than the classical Haversine formula: it seems one should always use the improved formula, rather than Haversine. ycoord; double deltaY =. Follow. if you only want a random number between 0 and 100, you can use the following formula: Example int randomNum = (int)(Math. First observe, the manhattan formula can be decomposed into two independent sums, one for the difference between x coordinates and the second between y coordinates.
