Constructor & Destructor Documentation

QVComplex::QVComplex (  ) 

Default constructor.

Constructs a complex number object equal to zero.

Definition at line 31 of file qvcomplex.cpp.

Referenced by i(), operator*(), operator+(), operator-(), and operator/().

QVComplex::QVComplex ( const QVComplex &  complex  ) 

Copy constructor.

Creates a complex object copying the content from a given one.

Parameters:
complex complex to be copied.

Definition at line 32 of file qvcomplex.cpp.

QVComplex::QVComplex ( const double  real,
const double  imaginary = 0.0 
)

Common constructor.

Creates a new complex number object, specifying the real and imaginary parts.

Parameters:
real Real part of the complex number.
imaginary Imaginary part of the complex number.

Definition at line 33 of file qvcomplex.cpp.

QVComplex::QVComplex ( const QPointF &  point  ) 

Constructor from a QPointF.
