C-Sharp Abs Example – Code Sample Syntax
Purpose: – Illustrates using C-Sharp Abs Code Example.
Purpose:
Returns the absolute value for the data type that was passed in.
Syntax:
Abs(expression)
Abs(expression)
| Parameters | Description | expression | 1. decimal – returns decimal number 2. double – returns double-percision floating point number 3. int16 – returns 16-bit integer 4. int32 – returns 32-bit integer 5. int64 – returns 64-bit integer 6. sbyte – returns 8-bit signed integer 7. single – returns single-percision floating point number |
|---|
| Result Data Type | Description | Depends on input | 1. decimal – when input is decimal 2. double – returns double-percision floating point number 3. int16 – returns 16-bit integer 4. int32 – returns 32-bit integer 5. int64 – returns 64-bit integer 6. sbyte – returns 8-bit signed integer 7. single – returns single-percision floating point number |

// Purpose: Returns the absolute value for the data type that was passed in.
//
//
// Syntax: Abs(expression)
//
// Parameter1: expression - 1. decimal - returns decimal number
// 2. double - returns double-percision floating point number
// 3. int16 - returns 16-bit integer
// 4. int32 - returns 32-bit integer
// 5. int64 - returns 64-bit integer
// 6. sbyte - returns 8-bit signed integer
// 7. single - returns single-percision floating point number
//
// Result: Depends on input - 1. decimal - when input is decimal
// 2. double - returns double-percision floating point number
// 3. int16 - returns 16-bit integer
// 4. int32 - returns 32-bit integer
// 5. int64 - returns 64-bit integer
// 6. sbyte - returns 8-bit signed integer
// 7. single - returns single-percision floating point number
//
// Quick Example: Abs(-3.4) // Returns 3.4
//
//
//********************************************************************************
// This example is from http://idealprogrammer.com
Console.WriteLine("Example #1: Abs(1.33)");
decimal decNumber = 1.33M;
Console.WriteLine(Math.Abs(decNumber)); // Returns 1.33
//write blank line to make output easier to read
Console.WriteLine();
Console.WriteLine("Example #2: Abs(-3.4)");
double douNumber = -3.4;
Console.WriteLine(Math.Abs(douNumber)); // Returns 3.4
//write blank line to make output easier to read
Console.WriteLine();
Console.WriteLine("Example #3: Abs(-0)");
int Integer3 = Math.Abs(-0);
Console.WriteLine(Math.Abs(-0)); // Returns 0
//Prevent console from closing before you press enter
Console.ReadLine();

Prerequistes:
- Install C-Sharp (Express or Standard Edition)
- Install SQL Server Express
- Download Northwind and pubs Database
- Attach Northwind Database to Databases in Sql Express
- 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:
- Use C-Sharp 2010 Express or Standard Edition
- Create new project;
- Click File/New Project
- Select Console Application Template
- Select C-Sharp for Language
- name of project could be C-Sharp_Syntax.
- Add New folder named “Functions”
- Right-click project name in solution explorer;
- add new folder;
- name of folder could be: Functions
- Add New subfolder named “MathFunctions”
- Right-click Functions folder in solution explorer;
- add new folder;
- name of folder could be: MathFunctions
- Add Class Named clsAbs to MathFunctions folder
- Right-click MathFunctions folder;
- add new item;
- Select class
- Class name could be clsAbs
- Click on cs in code in step 1 above to copy code into clsAbs.cs
- Click on cs in code in step 2 above to copy code into Module1.cs
- Click green arrow or press F5 to run program
