Complex Widening Conversion (Double to Complex)
Defines an implicit conversion of a double-precision floating-point number to a complex number.
Assemblies: System.Runtime.Numerics (in System.Runtime.Numerics.dll)

'Declaration Public Shared Widening Operator CType ( _ value As Double _ ) As Complex
- Type: System.Double
The value to convert to a complex number.
Return ValueType: System.Numerics.Complex
An object that contains the value of the value parameter as its real part and zero as its imaginary part.
The overloads of the Widening operator define the types from which a compiler can automatically convert a Complex object without an explicit casting operator (in C#) or a call to a conversion function (in Visual Basic). They are widening conversions that do not involve data loss and do not throw an OverflowException.
This overload lets the compiler handle conversions from a Double value to a complex number, as the following example shows. Note that the result of the conversion is a complex number whose real part is equal to the Double value and whose imaginary part is equal to zero.
