Complex.Multiply Operator

Multiplies two specified complex numbers.

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

public static Complex operator *(
	Complex left,
	Complex right


Type: System.Numerics.Complex
The first value to multiply.
Type: System.Numerics.Complex
The second value to multiply.

Return Value

Type: System.Numerics.Complex
The product of left and right.

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

Complex c1 = Complex.One;
Complex c2 = new Complex(1.4, 2.3);
Complex c3 = c1 * c2;

The multiplication of a complex number, a + bi, and a second complex number, c + di, takes the following form:

(ac - bd) + (ad + bc)i

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

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