3.3 Logical Operations on Complex Numbers (.NET, C#, CSharp, VB, Visual Basic, F#)

Operator == tests for equality of two complex numbers, and returns true if left.Real==right.Real and left.Imag==right.Imag; otherwise, false. Following the convention of the .NET Framework, if both objects are null, they test equal. Operator != returns the logical negation of ==.

The Equals() member function also tests for equality. NaNEquals() ignores values that are Not-a-Number (NaN).

NOTE—NMath provides no comparison operators for FloatComplex and DoubleCom­plex because there is no standard ordering for complex numbers.
