C-Sharp BigMul Example – Code Sample Syntax
C-Sharp BigMul Example – Code Sample Syntax
Purpose: – Illustrates using C-Sharp BigMul Code Example.
Purpose:
takes 2 32-bit integer numbers and returns their full
product as a 64-bit integer
Syntax:
BigMul(int1 as Int32, int2 as Int32)
BigMul(int1 as Int32, int2 as Int32)
Parameters | Description | int1 | Int32 |
---|---|
int2 | Int32 |
Result Data Type | Description | 64 bit integer | full product of 2 inputs |
---|
Quick Example | BigMul(Int32.MaxValue,Int32.MaxValue) // Returns 4611686014132420609 |
---|
Step 1: Click cs to Cut-n-paste code into clsBigMul.cs
using System; public class clsBigMul { public void Main() { //******************************************************************************** // Purpose: takes 2 32-bit integer numbers and returns their full // product as a 64-bit integer // // Syntax: BigMul(int1 as Int32, int2 as Int32) // // Parameter1: int1 - Int32 // // Parameter2: int2 - Int32 // // Result: 64 bit integer - full product of 2 inputs // // Quick Example: BigMul(Int32.MaxValue,Int32.MaxValue) // Returns 4611686014132420609 // //******************************************************************************** // This example is from http://idealprogrammer.com Console.WriteLine("Example #1: BigMul(Int32.MaxValue,Int32.MaxValue)"); Int32 int1 = Int32.MaxValue; Int32 int2 = Int32.MaxValue; Int64 result = 0; result = Math.BigMul(int1, int2); Console.WriteLine(result); // Returns 4611686014132420609 //Prevent console from closing before you press enter Console.ReadLine(); } } |
Step 2: Click cs to Cut-n-paste code into Module1.cs
Module Module1 Sub Main() Dim myclsBigMul As New clsBigMul myclsBigMul.Main() End Sub End Module |

Notes:
- Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
- You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Module1.cs
