C-Sharp Floor Example – Code Sample Syntax
C-Sharp Floor Example – Code Sample Syntax
Purpose: – Illustrates using C-Sharp Floor Code Example.
Purpose:
takes a decimal or double number and returns a value
that represents the next equal or lower whole number.
Although the result is a whole number, it is returned as a
the same data type that was passed in. Math.Ceiling is different
in that it rounds up to the next whole number that is equal
or greater than the number that is given.
Syntax:
Floor(decimalnumber)
Floor(decimalnumber)
Parameters | Description | decimalnumber | decimal number |
---|
Result Data Type | Description | decimal | closest whole number equal or lower |
---|
Syntax2:
Floor(doublenumber)
Floor(doublenumber)
Parameters | Description | doublenumber | double precision floating point number |
---|
Result Data Type | Description | double precision floating point number | closest whole number equal or lower |
---|
Quick Example | Floor(1.32) // Returns 1 |

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 clsFloor to MathFunctions folder
- Right-click MathFunctions folder;
- add new item;
- Select class
- Class name could be clsFloor
- Click on cs in code in step 1 above to copy code into clsFloor.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
