Gets the phase of a complex number.
Assembly: System.Numerics (in System.Numerics.dll)
For a complex number a + bi, the phase is computed as Math.Atan2(b, a).
You can identify a complex number by its Cartesian coordinates on the complex plane or by its polar coordinates. The phase (argument) of a complex number is the angle to the real axis of a line drawn from the point of origin (the intersection of the x-axis and the y-axis) to the point represented by the complex number. The magnitude (represented by the Magnitude property) is the distance from the point of origin to the point that is represented by the complex number.
You can instantiate a complex number based on its polar coordinates instead of its Cartesian coordinates by calling the FromPolarCoordinates method.
To convert the phase from radians to degrees, multiply it by 180/Math.PI.
