LI BRE OFFICE Calc

Li bre office calc is the spread sheet component of  li bre office software package .. calc is also capable of saving spread sheets as PDF Files
as with the entire Libre office suite ,Calc is available for variety of platform,including Linux 
OS X , MICROSOFT WINDOW AND FREE BSD

THE MAX.NO:OF COLUMNS is    1024         (FROM 'A' TO 'AMJ')
THE MAX. NO.:OF ROWS is         1048,576(2 to the power of 20)
THE MAX.NO: OF CELLS IN ONE SHEET IS  1073741824 (2 TO THE POWER OF 30
 ,WHICH IS MORE THAN ONE BILLION CELLS)

Libre office Calc features:

Calculations:-

Libre office calc provides you with function s, including statistical and banking functions,that you can use to create formula to perform complex calculations on your data you can also use the function Wizard,  help you to create your formulas.

WHAT--If calculations:

An interesting feature is to be able  to immediately view the results of changes made to one factor of calculations that are composed of several factors.

example:-  You can see how changing the time period in a LOAN calculations affects the interest rates or repayment amounts.Further more ,you can manage largest Tables by using 
different predefined scenarios .

SPREAD SHEET

WHAT IS THE PURPOSE OF A SPREAD SHEET ?

 A spread sheet is used to organize and categorize information in to easily readable and understandable columns and rows. Both large and small business can utilize spreadsheet to keep track of important data.

WHAT IS ELECTRONIC SPREADSHEET ?

A spread sheet is a computer application that displays and organize data. Each data is stored in a cell of a worksheet and can be manipulated using formulas to calculate or change the data in other cells . The spread sheet originated as an electronic equivalent of paper accounting sheet.

WHAT IS A VARIABLE IN A SPREADSHEET ?

A variable in spreadsheet is unit of storage that can change to any value or state at any time. The word variable can also be used to refer to the value itself

There are different type of variable including numeric variables,memory addresses and character variables  . To make referencing  the variable easier one should name the variable used in the calculation. Variables help make calculations in the spread sheet more flexible, there fore ,in spread sheet ,one can just change the value of variables and repeat the calculation. without them ,it would mean changing the whole calculation .It is also possible to use a range of cells as a variable. In such a case ,they are operated upon as a single unit.

FEATURES

 1,Visual Design: spread sheet s allow you to lay figures out on a grid ,calculating and manipulating them visually .
 2.Automatic calculations: Spread sheet software gives you the ability to enter mathematical formulas ranging from simple arithmetic to complex statistics. This is done in a simple and int restive manner, to perform a calculation with two different cells on the spread sheet Simply click a cell,press a key for mathematical operator such as the '+' sign and click the second cell . This is often a much faster to perform calculation with your data than a calculator do .

3.Dynamic Updates:

In addition to the standard method of entering in a spread sheet ..typing  number in cell...you can create a cell with a value generated dynamic ally based on other cells.Any time you base the value of one cell on the value of other cells, the value of one cell on the update automatically when the other is changed.

4.Data analysis:

Spread sheet software gives you the ability to analysis your data in ways other than simply looking at grids and lines. Most spread sheet software can arithmetically create graphs and chart from your data,giving you different ways of comparing and analyzing information can also be printed and  e.mailed or exported into slide show presentation .
