complex( const T& re = T(), const T& im = T() );	(1)
complex( const complex& other );	(2)

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.

Parameters

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