public phase() as Double:
Returns the phase (or angle) of the complex number in radians.
The phase of the complex number in radians. c = Complex<>(1, 1) print(c.phase()) # Output: 0.7853981633974483 (approximately π/4)
c = Complex<>(1, 1) print(c.phase()) # Output: 0.7853981633974483 (approximately π/4)
