Math::BigMul Method (Int32, Int32)


Produces the full product of two 32-bit numbers.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

static long long BigMul(
	int a,
	int b


Type: System::Int32

The first number to multiply.

Type: System::Int32

The second number to multiply.

Return Value

Type: System::Int64

The number containing the product of the specified numbers.

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
