::mfp::math::complex::abs(1) :

abs(x) returns modulus of a complex number or absolute value of a real number.

::mfp::math::complex::angle(1) :

angle(x) returns radian based angle of a complex number

::mfp::math::complex::image(1) :

image(x) returns image part (a real value) of complex value x.

::mfp::math::complex::image(2) :

image(x, mode) returns image part of complex value x. If mode is true, returns image value. Otherwise, returns real value. For example, image(3+2i, true) = 2i while image(3+2i, false) = 2.

::mfp::math::complex::real(1) :

real(x) returns real part of complex value x.
