The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Returns a value that indicates whether two complex numbers are not 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 value to compare.

right
Type: System.Numerics.Complex

The second value to compare.

Return Value

Type: System.Boolean

true if left and right are not equal; otherwise, false.

The Equality method defines the operation of the inequality operator for complex numbers. 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 test for inequality by calling the Equals(Complex) method and reversing its value.

Note that, because of differences in precision, two complex numbers that are apparently equivalent can be considered unequal. One possible workaround is to implement a comparison method that returns true only if the difference between the two real and imaginary parts of the complex numbers exceeds a certain threshold (such as .01% of the value of the real or imaginary component of one of the complex numbers). For more information, see the Equals(Complex) method.
