Tim, I need more precision than rounding to the nearest integer, but thank you. Lampei, that solution sounded perfect at first but I was running into problems when I started passing over 900 points to be compared. Sam, this looks like exactly what I am looking for. My test cases seem to be passing so far and all is well. Thank you for all the quick responses. fumeng.
