public static long BigMul(
	int a,
	int b
)

Parameters

a
Type: System.Int32

The first number to multiply.

b
Type: System.Int32

The second number to multiply.

Return Value

Type: System.Int64

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

// 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);
    }
}
/*
This example produces the following results:
Calculate the product of two Int32 values:
2147483647 * 2147483647 = 4611686014132420609
