Complex.Subtraction Operator

Silverlight

Subtracts a complex number from another complex number.

Namespace: System.Numerics
Assembly: System.Numerics (in System.Numerics.dll)

public static Complex operator -(
	Complex left,
	Complex right
)

Parameters

left: Type: System.Numerics.Complex
The value to subtract from (the minuend).

right: Type: System.Numerics.Complex
The value to subtract (the subtrahend).

Return Value

Type: System.Numerics.Complex
The result of subtracting right from left.

Remarks

The Subtraction method defines the operation of the subtraction operator for complex numbers. It enables code such as the following:


System.Numerics.Complex c1 = new System.Numerics.Complex(6.7, -1.3);
System.Numerics.Complex c2 = new System.Numerics.Complex(1.4, 3.8);
System.Numerics.Complex result = c1 - c2;
outputBlock.Text += String.Format("{0} - {1} = {2}", c1, c2, result) + "\n";
// The example displays the following output:
//       (6.7, -1.3); - (1.4, 3.8); = (5.3, -5.1)

If the method call results in an overflow in either the real or imaginary component, the value of that component is either Double.PositiveInfinity or Double.NegativeInfinity.

The subtraction of a complex number, c + di, from another complex number, a + bi, takes the following form:

(a - c) + (b - d)i

Languages that do not support custom operators can call the Subtract method instead.
