C-Sharp Truncate Example – Code Sample Syntax

C-Sharp Truncate Example – Code Sample Syntax

Purpose: – Illustrates using .

Purpose:
takes a decimal or double as input parameter1
and returns the number truncated without the
fractional decimals.

Syntax:
1. Truncate(decimal)
2. Truncate(double)

Parameters Description
decimal Any valid System.Decimal data type number
double – any valid System.Double data type.
Parameter1 specifies the number to be Truncated

Result Data Type Description
decimal or double depends on data type
of parameter1. It is decimal, if parameter1 is
decimal. If parameter1 is double, result is double.

Quick Example
Truncate(3.5) // Returns 3

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

using System;
public class clsTruncate
{
 
    public void Main()
    {
 
 
        //********************************************************************************
        // Purpose: takes a decimal or double as input parameter1

        // Syntax: 	1. Truncate(decimal)

        //  
        // Parameter1: decimal - Any valid System.Decimal data type number
        // double - any valid System.Double data type.
        // Parameter1 specifies the number to be Truncated
        //
        // Result: decimal or double - depends on data type
        // of parameter1. It is decimal, if parameter1 is 
        // decimal. If parameter1 is double, result is double.

        //
        //********************************************************************************
        // This example is from http://idealprogrammer.com
 
        Console.WriteLine("Example #1: 	Truncate(decimal)");
 
        Console.WriteLine("Truncate(3.5) = {0}", Math.Truncate(3.5)); // Returns 3
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
        Console.WriteLine("Example #2: 	Truncate(double)");
        double myDouble = 6.5;
        Console.WriteLine("Truncate(myDouble) = {0}", Math.Truncate(myDouble)); // Returns 6
        //write blank line to make output easier to read
        Console.WriteLine();
 
        Console.WriteLine("Example #3: 	Truncate(decimal)");
 
 
 
        Console.WriteLine("Truncate(0.9) = {0}", Math.Truncate(0.9)); // Returns 0
 
        //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 myclsTruncate As New clsTruncate
        myclsTruncate.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 Truncate

  1. Use C-Sharp 2010 Express or Standard Edition
  2. Create new project;
    • Click File/New Project
    • Select Console Application Template

  3. Add New folder named “Functions”
    • Right-click project name in solution explorer;
    • add new folder;
    • name of folder could be: Functions
  4. Add New subfolder named “MathFunctions”
    • Right-click Functions folder in solution explorer;
    • add new folder;
    • name of folder could be: MathFunctions
  5. Add Class Named clsTruncate to MathFunctions folder
    • Right-click MathFunctions folder;
    • add new item;
    • Select class
    • Class name could be clsTruncate
  6. Click on cs in code in step 1 above to copy code into clsTruncate.cs
  7. Click on cs in code in step 2 above to copy code into Module1.cs
