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

public Decimal(
	ulong 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 Example
   // Create a decimal object and display its value.
   public static void CreateDecimal(System.Windows.Controls.TextBlock outputBlock, 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.
      outputBlock.Text += String.Format("{0,-35}{1,22}", ctor, decimalNum) + "\n";

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
      outputBlock.Text += "This example of the decimal( ulong ) " +
          "constructor \ngenerates the following output.\n" + "\n";
      outputBlock.Text += String.Format("{0,-35}{1,22}", "Constructor", "Value") + "\n";
      outputBlock.Text += String.Format("{0,-35}{1,22}", "-----------", "-----") + "\n";

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

This example of the decimal( ulong ) constructor
generates the following output.

Constructor                                         Value
-----------                                         -----
decimal( ulong.MinValue )                               0
decimal( ulong.MaxValue )            18446744073709551615
decimal( long.MaxValue )              9223372036854775807
decimal( 999999999999999999 )          999999999999999999
decimal( 0x2000000000000000 )         2305843009213693952
decimal( 0xE000000000000000 )        16140901064495857664
