	int a, 
	int b
)

Parameters

Examples

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

C++


// 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
