Hi,
Thanks to everyone who replied, I do appreciate it. The reason I wrote is that I *did* go through the JavaDocs, and they were no help (even Surasak Leenapongpanit's reposting of the atan() API says nothing about radians); I Googled for about half an hour as well, to no avail. Believe me, I do all the research I reasonably can before posting!
