Return imaginary part of complex
Returns the imaginary part of the complex number x.
The imaginary part is the factor by which the imaginary unit is multiplied.
The function simply calls x's member function imag.
Parameters
- x
- Complex value.
Return value
Imaginary part of x.
T is x's complex template type (i.e., its value type).
