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.
Parameters
| re | - | the real part |
| im | - | the imaginary part |
| other | - | another complex to use as source |
