ATan2

A command for Oblivion Script Extender

Syntax:

atan2 [float1] [float2]

or

datan2 [float1] [float2]

Returns the angle of (float2;float1) vector

Example

set theta to atan2 y x

Notes

• 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.
