C# BigInteger Explicit(BigInteger to Double)
Description
BigInteger Explicit(BigInteger to Double) Defines
an explicit conversion of a BigInteger object to a Double value.
Syntax
BigInteger.Explicit(BigInteger to Double) has the following syntax.
public static explicit operator double (
BigInteger value
)
Parameters
BigInteger.Explicit(BigInteger to Double) has the following parameters.
value- The value to convert to a Double.
Returns
BigInteger.Explicit(BigInteger to Double) method returns An object that contains the value of the value parameter.
Example
/*from w ww . ja v a 2 s . c o m*/
using System;
using System.IO;
using System.Numerics;
public class Example
{
public static void Main()
{
BigInteger number1 = (BigInteger) Double.MaxValue;
BigInteger number2 = number1;
number2 = number2 + (BigInteger) 9.999e291;
Console.WriteLine("BigIntegers equal: {0}", number2.Equals(number1));
double dbl = (double) number2;
Console.WriteLine("BigInteger: {0}", number2);
Console.WriteLine("Double: {0}", dbl);
BigInteger goodDouble = (BigInteger) 102.43e22;
BigInteger badDouble = (BigInteger) Double.MaxValue;
badDouble = badDouble * 2;
double doubleFromBigInteger;
// successful conversion using cast operator.
doubleFromBigInteger = (double) goodDouble;
Console.WriteLine(doubleFromBigInteger);
// Convert an out-of-bounds BigInteger value to a Double.
doubleFromBigInteger = (double) badDouble;
Console.WriteLine(doubleFromBigInteger);
}
}
The code above generates the following result.
