C# BigInteger Explicit(BigInteger to UInt64)
Description
BigInteger Explicit(BigInteger to UInt64) Defines
an explicit conversion of a BigInteger object to an unsigned 64-bit integer
value.
Syntax
BigInteger.Explicit(BigInteger to UInt64) has the following syntax.
public static explicit operator ulong (
BigInteger value
)
Parameters
BigInteger.Explicit(BigInteger to UInt64) has the following parameters.
value- The value to convert to an unsigned 64-bit integer.
Returns
BigInteger.Explicit(BigInteger to UInt64) method returns An object that contains the value of the value parameter.
Example
/*from www . j a v a 2 s .c o m*/
using System;
using System.IO;
using System.Numerics;
public class Example
{
public static void Main()
{
// BigInteger to UInt64 conversion.
BigInteger goodULong = 2000000000;
BigInteger badULong = BigInteger.Pow(goodULong, 3);
ulong uLongFromBigInteger;
// Successful conversion using cast operator.
uLongFromBigInteger = (ulong) goodULong;
Console.WriteLine(uLongFromBigInteger);
// Handle conversion that should result in overflow.
try
{
uLongFromBigInteger = (ulong) badULong;
Console.WriteLine(uLongFromBigInteger);
}
catch (OverflowException e)
{
Console.WriteLine("Unable to convert {0}:\n {1}",
badULong, e.Message);
}
}
}
The code above generates the following result.
