C# BigInteger LeftShift
Description
BigInteger LeftShift Shifts a BigInteger value a specified
number of bits to the left.
Syntax
BigInteger.LeftShift has the following syntax.
public static BigInteger operator <<(
BigInteger value,
int shift
)
Parameters
BigInteger.LeftShift has the following parameters.
value- The value whose bits are to be shifted.shift- The number of bits to shift value to the left.
Returns
BigInteger.LeftShift method returns A value that has been shifted to the left by the specified number of bits.
Example
// www . jav a2 s . co m
using System;
using System.IO;
using System.Numerics;
public class Example
{
public static void Main()
{
BigInteger number = BigInteger.Parse("-12312312312312312312312");
Console.WriteLine("Shifting {0} left by:", number);
for (int ctr = 0; ctr <= 16; ctr++)
{
BigInteger newNumber = number << ctr;
Console.WriteLine(" {0,2} bits: {1,35} {2,30}",
ctr, newNumber, newNumber.ToString("X"));
}
number = BigInteger.Parse("-1232123321231231231231");
Console.WriteLine("Shifting {0} left by:", number);
for (int ctr = 0; ctr <= 16; ctr++)
{
BigInteger newNumber = BigInteger.Multiply(number, BigInteger.Pow(2, ctr));
Console.WriteLine(" {0,2} bits: {1,35} {2,30}",
ctr, newNumber, newNumber.ToString("X"));
}
}
}
The code above generates the following result.
