C# BigInteger Explicit(BigInteger to Int64)
Description
BigInteger Explicit(BigInteger to Int64) Defines an
explicit conversion of a BigInteger object to a 64-bit signed integer value.
Syntax
BigInteger.Explicit(BigInteger to Int64) has the following syntax.
public static explicit operator long (
BigInteger value
)
Parameters
BigInteger.Explicit(BigInteger to Int64) has the following parameters.
value- The value to convert to a 64-bit signed integer.
Returns
BigInteger.Explicit(BigInteger to Int64) method returns An object that contains the value of the value parameter.
Example
/*w ww. jav a2s . c o m*/
using System;
using System.IO;
using System.Numerics;
public class Example
{
public static void Main()
{
// BigInteger to Int64 conversion.
BigInteger goodLong = 2000000000;
BigInteger badLong = BigInteger.Pow(goodLong, 3);
long longFromBigInteger;
// Successful conversion using cast operator.
longFromBigInteger = (long) goodLong;
Console.WriteLine(longFromBigInteger);
// Handle conversion that should result in overflow.
try
{
longFromBigInteger = (long) badLong;
Console.WriteLine(longFromBigInteger);
}
catch (OverflowException e)
{
Console.WriteLine("Unable to convert {0}:\n {1}",
badLong, e.Message);
}
}
}
The code above generates the following result.
