Decimal.ToUInt64() Method in C#
This method is used to convert the value of the specified Decimal to the equivalent 64-bit unsigned integer. A user can also convert a Decimal value to a 64-bit unsigned integer by using the Explicit assignment operator.
Syntax: public static ulong ToUInt64 (decimal d);
Here, the d is the decimal number which is to be converted.
Return Value: It returns a 64-bit unsigned integer equivalent to the specified value i.e. d.
Exception: This method will give OverflowException if the specified value is negative or greater than MaxValue.
Below programs illustrate the use of the above-discussed method:
Example 1:
// C# program to demonstrate the // Decimal.ToUInt64(Decimal) Method using System; class GFG { // Main Method public static void Main() { try { // Taking decimal variables Decimal dec1 = 9223372036854775807.999m; Decimal dec2 = 18446744073709551615.784m; // using Decimal.ToUInt64(Decimal) Method ulong val1 = Decimal.ToUInt64(dec1); // using Decimal.ToUInt64(Decimal) Method ulong val2 = Decimal.ToUInt64(dec2); // Printing the UInt64 value Console.WriteLine( "The UInt64 value " + "is : {0}" , val1); // Printing the UInt64 value Console.WriteLine( "The UInt64 value " + "is : {0}" , val2); } catch (OverflowException e) { Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
Output:
The UInt64 value is : 9223372036854775807 The UInt64 value is : 18446744073709551615
Example 2: For OverflowException
// C# program to demonstrate the // Decimal.ToUInt64(Decimal) Method using System; class GFG { // Main Method public static void Main() { try { // Taking the maximum value // of Decimal Decimal dec1 = Decimal.MaxValue; // using Decimal.ToUInt64(Decimal) Method // It will give error as decimal number // is above the range of UInt64 ulong val1 = Decimal.ToUInt64(dec1); // Printing the UInt64 value Console.WriteLine( "The UInt64 value " + "is : {0}" ,val1); } catch (OverflowException e) { Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
Output:
Exception Thrown: System.OverflowException
