Constructs the std::complex
object.
1) Constructs the complex number from real and imaginary parts.
2) Copy constructor. Constructs the object with the copy of the contents of
other
. The copy constructor is implicit in the standard specializations.
3) Converting constructor. Constructs the object from a complex number of a different type.
Parameters
re | - | the real part |
im | - | the imaginary part |
other | - | another complex to use as source |
