 Hello, I thought i know how atan2 works, but i am very surrprised. Results that i get are strange. Please help me and let me know: -how to obtaint an angle for a strait line (i know its directional rate - gradient) in the first quarter of coordinate arrangement, or -how atan2 exactly works, or -at last how to calculate arcus tangens in other way. Thanks in advance.

 Yea, it is a little confusing once you first start working with it. We basically just mapped the C++ version of atan2. For more description on that have a look at http://www.cplusplus.com/reference/clibrary/cmath/atan2.html Some tips are: - Convert to degrees (atan2(100,100)*180.0f)/3.14159 - Convert to 0 - 2PI range deg = atan2(100,100) if deg < 0 then deg = 6.2831853 + deg - Convert to 0 - 360 range deg = (atan2(100,100)*180.0f)/3.1415927 if deg < 0 then deg = 6.2831853 + deg STeven.
