Complex Implicit Conversion (UInt64 to Complex)

Defines an implicit conversion of a 64-bit unsigned integer to a complex number.

This API is not CLS-compliant. 

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


Public Shared Widening Operator CType ( _

public static implicit operator Complex (
    ulong value


  • value
    Type: System.UInt64
    The value to convert to a complex number.

Return Value

Type: 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 Implicit 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 an unsigned 64-bit integer 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 unsigned 64-bit integer and whose imaginary part is equal to zero.

Dim longValue As ULong = 951034217
Dim c1 As System.Numerics.Complex = longValue
outputBlock.Text &= c1.ToString() + vbCrLf
' The example displays the following output:
'       (951034217, 0)
ulong longValue = 951034217;
System.Numerics.Complex c1 = longValue;
outputBlock.Text += c1 + "\n";
// The example displays the following output:
//       (951034217, 0)
