Arc Tangent 2

Overview

The Arc Tangent 2 Node.
The Arc Tangent 2 Node takes two Float values,
yy
 and
xx
, and returns
atan2(y,x)atan2(y,x)
. The result can be obtained in degrees (°) or radians (rad).
The function
atan2(y,x)atan2(y,x)
 is of common use in computer science and can be equivalently defined as:
  • The angle
    θ\theta
     in the Euclidean plane between the positive
    XX
     axis and the ray connecting the origin and the point
    (x,y)(x,y)
    .
  • The phase
    θ\theta
     of the complex number
    x+iyx+iy
    . That is, the angle
    θ∈(−π,π]\theta \in (-\pi, \pi]
     such that
    x=rcos⁡θx=r\cos\theta
     and
    y=rsin⁡θy=r\sin\theta
    , where
    r=x2+y2r=\sqrt{x^2+y^2}
    .
