C++

public Complex( 
   double r, 
   double i 
)

Public Function New( _ 
   ByVal r As Double, _ 
   ByVal i As Double _ 
)

public Complex(double r, double i)

public: 
Complex(  
   double r, 
   double i 
)

Parameters

r
Real part of a complex number.

i
Imaginary part of a complex number.

Example

Define a complex number.

   // Prepare the command 
   // Set the real and the imaginary part of the complex number. 
   Complex com = Complex.Empty;
