Decimal Widening Conversion (UInt64 to Decimal)

Converts a 64-bit unsigned integer to a Decimal.

This API is not CLS-compliant. 

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

'Declaration
Public Shared Widening Operator CType ( _
	value As ULong _
) As Decimal

Parameters

value
Type: System.UInt64
The 64-bit unsigned integer to convert.

Return Value

Type: System.Decimal
The converted 64-bit unsigned integer.

The following code example converts UInt64 values to Decimal numbers using the UInt64 to Decimal conversion. This conversion is implicit in C#, but requires the op_Implicit operator in Visual Basic and C++. Implicit conversions to Decimal use other methods in these languages.

        Dim bits( )     As Integer

        ' The compiler invokes a constructor in Visual Basic 
        ' unless op_Implicit is explicitly called.
        decValue = Decimal.op_Implicit( argument )

        ' Display the Decimal and its binary representation.
        bits = Decimal.GetBits( decValue )
