asp.net (C #) complex class (Complex subtraction Arithmetic) _ Practical Tips

One of my Java jobs, I changed it to ASP.net (C #).

Copy Code code as follows:

protected void Page_Load (object sender, EventArgs e)
{
Complex complex_a = new Complex (1.0, 1.0);
Complex Complex_b = new Complex (2.0, 2.0);
Response.Write ("Addition operation result:" + complex_a.complex_add (Complex_b). ToString () + "<br/>");
Response.Write ("Subtraction Result:" + Complex_a.complex_minus (Complex_b). ToString () + "<br/>");
Response.Write ("Multiplication Result:" + complex_a.complex_multi (Complex_b). ToString () + "<br/>");
Response.Write ("Division operation result:" + complex_a.complex_divide (Complex_b). ToString ());
}

public class Complex
{
The real part in the plural
Private double complex_real;
Imaginary part in a complex number
Private double complex_imagin;

Constructors
Public complex (double R, double i)
{
Complex_real = R;
Complex_imagin = i;
}

Overriding the ToString () method
public override string ToString ()
{
return this.complex_real + "+" + this.complex_imagin + "I";
}

Complex number addition operation
Public complex Complex_add (complex c)
{
Get the real part after the addition operation
Double complex_real = this.complex_real + c.complex_real;

To obtain the imaginary part after the addition operation
Double Complex_imagin = This.complex_imagin + c.complex_imagin;

Returns a complex number class
return new complex (Complex_real,complex_imagin);
}

Complex subtraction operation
Public complex Complex_minus (complex c)
{
Gets the real part after the subtraction operation
Double complex_real = this.complex_real-c.complex_real;

To obtain the imaginary part after the subtraction operation
Double complex_imagin = This.complex_imagin-c.complex_imagin;

Returns a complex number class
return new Complex (Complex_real, complex_imagin);
}

Multiplication operations
Public complex Complex_multi (complex c)
{
Get the real part after the multiplication operation
Double complex_real = this.complex_real * C.complex_real-this.complex_imagin * c.complex_imagin;

To obtain the imaginary part after multiplication operation
Double Complex_imagin = this.complex_real * c.complex_imagin + this.complex_imagin * c.complex_real;

Returns a complex number class
return new Complex (Complex_real, complex_imagin);
}

Division result (A+BI)/(C+di) = (A+bi) (C-di)/(C+di) (C-di)
Public complex Complex_divide (complex c)
{
Gets the value of (C+di) (C-di)
Double d = c.complex_real * c.complex_real + c.complex_imagin * c.complex_imagin;

Get the real part after the division operation
Double complex_real = (This.complex_real * c.complex_real + this.complex_imagin * c.complex_imagin)/D;

To obtain the imaginary part after division operation
Double Complex_imagin = (This.complex_real * (-c.complex_imagin) + this.complex_imagin * c.complex_real)/D;

Returns a complex number class
return new Complex (Complex_real, complex_imagin);
}
}

Run Result:

Copy Code code as follows:

addition operation result:3+3i  
Subtraction result:-1+-1i  
Multiplication Result: 0+4i& nbsp; 
Division results:0.5+0i
