What kind of math would I use to calculate the difference between two degrees on a circle? Say, 38 and 272 degrees? When I just subtract one position from another sometimes it's more than 180 or sometimes I cross over 0/360. I need keywords that can help me learn more about it. Ultimately I want to create an excel formula but I don't know what it is called. Thanks

0Maybe you're looking for the [modulo](http://en.wikipedia.org/wiki/Modular_arithmetic) operation? – 2012-08-23

0yes may be modulo $2\pi$? – 2012-08-23

0@Seyhmus or $\bmod 360$, if you want to keep things entirely in degrees. – 2012-08-23

0@J.M. sure it seems more interesting) – 2012-08-23
