I've reimplemented tons of APIs when they didn't work. But it occurs to me now that this could simply be a documentation error.
-90 and 270 are equivalent. I assumed the OP knows that, and was still unhappy with the result. Perhaps he wants to verify the result. A bit of googling and a calculator will suffice. The documentation SAYS that it returns it in degrees east of true north, which *I* interpret as being the positive number of degrees you have to turn to the east to get to that bearing. I also claim that's what it SHOULD return, for various minor reasons. But the only critical thing is that it BE CLEARLY DOCUMENTED and BEHAVE AS DOCUMENTED. I haven't tried it myself, but if he's right, it fails one of those. In any event, even if the API is working as designed, I think a bug report is in order; the ambiguity in the doc at a minimum should be fixed.
