Decimal Constructor (UInt64)

Initializes a new instance of Decimal to the value of the specified 64-bit unsigned integer.

This API is not CLS-compliant. 

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

[CLSCompliantAttribute(false)]
public Decimal(
	ulong value
)

Parameters

value
Type: System.UInt64

The value to represent as a Decimal.

The following code example creates several Decimal numbers using the constructor overload that initializes a Decimal structure with a UInt64 value.

// Example of the decimal( ulong ) constructor. 
using System;

class DecimalCtorLDemo
{
    // Create a decimal object and display its value. 
    public static void CreateDecimal( ulong value, string valToStr )
    {
        decimal decimalNum = new decimal( value );

        // Format the constructor for display. 
        string ctor = String.Format( "decimal( {0} )", valToStr );

        // Display the constructor and its value.
        Console.WriteLine( "{0,-35}{1,22}", ctor, decimalNum );
    }

    public static void Main( )
    {
        Console.WriteLine( "This example of the decimal( ulong ) " +
            "constructor \ngenerates the following output.\n" );
        Console.WriteLine( "{0,-35}{1,22}", "Constructor", "Value" );
        Console.WriteLine( "{0,-35}{1,22}", "-----------", "-----" );

        // Construct decimal objects from ulong values.
        CreateDecimal( ulong.MinValue, "ulong.MinValue" );
        CreateDecimal( ulong.MaxValue, "ulong.MaxValue" );
        CreateDecimal( long.MaxValue, "long.MaxValue" );
        CreateDecimal( 999999999999999999, "999999999999999999" );
        CreateDecimal( 0x2000000000000000, "0x2000000000000000" );
        CreateDecimal( 0xE000000000000000, "0xE000000000000000" );
    }
}
