# Convert Decimal to the equivalent 64-bit unsigned integer in C#

To convert the value of the specified Decimal to the equivalent 64-bit unsigned integer, the code is as follows −

## Example

Live Demo

using System;
public class Demo {
public static void Main() {
Decimal val = 99.29m;
Console.WriteLine("Decimal value = "+val);
ulong res = Decimal.ToUInt64(val);
Console.WriteLine("64-bit unsigned integer = "+res);
}
}

## Output

This will produce the following output −

Decimal value = 99.29
64-bit unsigned integer = 99

## Example

Let us see another example −

Live Demo

using System;
public class Demo {
public static void Main(){
Decimal val = 0.001m;
Console.WriteLine("Decimal value = "+val);
ulong res = Decimal.ToUInt64(val);
Console.WriteLine("64-bit unsigned integer = "+res);
}
}

## Output

This will produce the following output −

Decimal value = 0.001
64-bit unsigned integer = 0
