Syntax:
atan2 [float1] [float2]
or
datan2 [float1] [float2]
Returns the angle of (float2;float1) vector
Example[edit | edit source]
set theta to atan2 y x
Notes[edit | edit source]
- Returns a value from 0 to 180 or 0 to -180
- 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. ratan2)
- This function can be used in a mathematical formula (c + atan2 a b), but a mathematical formula as the arguement for this function will not give correct result (the result of atan2 a (b + c) will be a+b+c).
- For a right triangle, the first float is the opposite side and the second float the adjacent side.
