C-Sharp Pow Example – Code Sample Syntax

C-Sharp Pow Example – Code Sample Syntax

Purpose: – Illustrates using .

Purpose:
takes two double data type numbers and raises the
first number to the power of the second. The result is
returned as a double data type.

Syntax:
Pow(doublenumberbase, doublenumberpower)

Parameters Description
doublenumberbase Any valid System.Double data type number
This is the number that will raised to the power
specified in the second parameter
doublenumberpower Any valid System.Double data type number
This is the number that used as the power
to be applied to the first parameter

Result Data Type Description
double returns the first parameter raised to the power
of the second input parameter

Quick Example
Pow(2,3) // Returns 8

Step 1: Click cs to Cut-n-paste code into clsPow.cs

using System;
public class clsPow
{
 
    public void Main()
    {

        // Purpose: takes two double data type numbers and raises the

        //
        // Syntax: 	Pow(doublenumberbase, doublenumberpower)
        //  
        // Parameter1: doublenumberbase - Any valid System.Double data type number
        // This is the number that will raised to the power 
        // specified in the second parameter
        //
        // Parameter2: doublenumberpower - Any valid System.Double data type number
        // This is the number that used as the power 
        // to be applied to the first parameter
        //

        Console.WriteLine("Example #1: 	Pow(doublenumberbase,doublenumberpower)");
 
        Console.WriteLine("Pow(2,3) = {0}", Math.Pow(2, 3)); // Returns 8
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
        Console.WriteLine("Example #2: 	Pow(doublenumberbase,doublenumberpower)");
 
        Console.WriteLine("Pow(5,2) = {0}", Math.Pow(5, 2)); // Returns 25
        //write blank line to make output easier to read
        Console.WriteLine();
 
        Console.WriteLine("Example #3: 	Pow(doublenumberbase,doublenumberpower)");
 
 
 
        Console.WriteLine("Pow(7,1) = {0}", Math.Pow(7, 1)); // Returns 7
 
        //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 myclsPow As New clsPow
        myclsPow.Main()
 
 
 
    End Sub
 
End Module

Prerequistes:

  1. Install C-Sharp (Express or Standard Edition)
  2. Install SQL Server Express
  3. Download Northwind and pubs Database
  4. Attach Northwind Database to Databases in Sql Express
  5. Attach pubs Database to Databases in Sql Express

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

Instructions:
C-Sharp Syntax Functions Pow

  1. Use C-Sharp 2010 Express or Standard Edition
  2. Create new project;
