Interesting link. Sorry, I don't mean to nit-pic, just to provide some clarification.

From a mathematical standpoint, "Brads" as referred to in the link, is a suggested misnomer as well, since radians play no role in the user's-end of the equation. Lacking any other existing unit, some new unit should be assigned. Since the nature of any angle measurement is that it cycles, similarities in this respect are moot point (since it's a requirement). I'm kind of partial to "Bangles", myself - Binary Angles where there are 256 units in a full cycle.

The difficulties I encountered while trying to implement SIN properly in my recent program was due to the fact that the manual provided no examples, and the wording was such that one would think that radians (by definition) were the actual unit of measurement (which they aren't, since the function doesn't repeat every 6.28 units). I hope this helps others who are trying to successfully implement this function.
