Complex.Equality Operator (Complex, Complex)

 
equivalentCodeEntityOverload:System.Numerics.Complex.Equals

Returns a value that indicates whether two complex numbers are equal.

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

public static bool operator ==(
	Complex left,
	Complex right
)

Parameters

left
Type: System.Numerics.Complex

The first complex number to compare.

right
Type: System.Numerics.Complex

The second complex number to compare.

Return Value

Type: System.Boolean

true if the left and right parameters have the same value; otherwise, false.

The Equality method defines the operation of the equality operator for Complex values. It enables code such as the following:

Complex c1 = new Complex(12.6, 4.3);
Complex c2 = new Complex(11.1, 8.9);
if (c1 == c2) 

Languages that do not support custom operators can call the Equals(Complex) method instead.

Two complex numbers are equal if their real parts are equal and their imaginary parts are equal. The Equality method is equivalent to the following expression:

return this.Real == value.Real && this.Imaginary == value.Imaginary;

Note that, because of differences in precision, two complex numbers that are apparently equivalent can be considered unequal. For more information and a possible workaround, see the Equals(Complex) method.
