Math.BigMul(Int32, Int32) Method

Definition

Produces the full product of two 32-bit numbers.

public static long BigMul (int a, int b);
Parameters
a
Int32

The first number to multiply.

b
Int32

The second number to multiply.

Returns

The number containing the product of the specified numbers.

Examples

The following example demonstrates the use of the BigMul method to calculate the product of two integer values.

// This example demonstrates Math.BigMul()
using namespace System;
int main()
{
   int int1 = Int32::MaxValue;
   int int2 = Int32::MaxValue;
   Int64 longResult;
   
   //
   longResult = Math::BigMul( int1, int2 );
   Console::WriteLine( "Calculate the product of two Int32 values:" );
   Console::WriteLine( "{0} * {1} = {2}", int1, int2, longResult );
}

/*
This example produces the following results:
Calculate the product of two Int32 values:
2147483647 * 2147483647 = 4611686014132420609
*/
// This example demonstrates Math.BigMul()
using System;

class Sample 
{
    public static void Main() 
    {
    int int1 = Int32.MaxValue;
    int int2 = Int32.MaxValue;
    long longResult;
//
    longResult = Math.BigMul(int1, int2);
    Console.WriteLine("Calculate the product of two Int32 values:");
    Console.WriteLine("{0} * {1} = {2}", int1, int2, longResult);
    }
}
