ComplexRadians


ComplexRadians(x)

Returns the phase of complex number «x» in radians.

A complex number can be written in polar form as $ r e^{\theta j} $. Given a complex number, «x», ComplexRadians returns $ \theta $, the result being expressed in radians in the range of $ [-\pi,\pi) $.

Examples

ComplexRadians(5 + 5j) → 0.7854 {This is $ \pi/4 $}
ComplexRadians(1j) → 1.571 {This is $ \pi/2 $}
ComplexRadians(-1j) → -1.571
ComplexRadians(-2) → -3.142
ComplexRadians(.1) → 0
