==Notes== | |||
*From v0005, all OBSE trigonometric functions take and return degrees. Versions of the functions which accept radians are still available by prefixing the function name with an r. (i.e. ratan) | |||
*This function can be used in a mathematical formula (a + atan b), but a mathematical formula will not compile as the arguement for this function (atan (a + b) doesn't work). | |||
*atan a + b = ( atan a ) + b | |||
