Przykłady

Poniższy przykład ilustruje użycie metody BigMul do obliczenia iloczynu dwóch wartości całkowitych.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);
    }
}
