# Complex.One Field

Returns a new Complex instance with a real number equal to one and an imaginary number equal to zero.

**Namespace:**System.Numerics

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

The following example instantiates a Complex value by using the One property. It then compares this value to another value that is instantiated by calling the Complex constructor with a real part equal to one and an imaginary part equal to zero. As the output from the example shows, the two values are equal.
