Atan2f atan2

The function atan2 computes the principal value of the argument function applied to the complex number x + i y. That is, atan2(y, x) = Pr arg(x + i y) = Arg(x + i y). The argument could be changed by an arbitrary multiple of 2π (corresponding to a complete turn around the origin) without making any difference to the angle, but to define atan2 uniquely one uses the principal value in the range , that is, … WebAtan2() is needed as atan() doesn't tell you the angle from the horizontal you need as it doesn't cope with quadrants. ... { float aThis = atan2f( y, x ); float aO = atan2f( o.y, o.x ) ; return aThis - aO ; } Share.
