Basic Functions : fixed
In OpenOffice Calc, the FIXED function returns a text representation of a number rounded to a specified number of decimal places.
The arguments to the function are :
FIXED(number, decimal_places, no_commas) where
number… is the number to round.
decimal_places is the number of decimal places to display in the result.
no_commas If this parameter is set to TRUE, the result will not display commas. If it is set to FALSE, it will display commas in the result.
We see a few examples of the FIXED function below.

Paste Special II - Removing formulae
September 20th, 2005
The paste special feature is useful for preserving the values in a spreadsheet - but removing the formulae that generated those values. This may be required to preserve proprietary equations.
To remove the formulae for a range of cells, select and copy the desired range. Do not unselect the range. Now click on Edit - Paste Special - see below.
Make sure the Formulas box is unchecked. After you click OK, the formula is removed but the value is preserved.

Secret StarWars games
September 16th, 2005
Open Office Calc has an interesting Easter egg - a hidden feature that might not be obvious or documented. Programmers sometimes bury Easter Eggs in their programs or web sites to add extra depth and challenge users to find them.
In an empty cell, type the following formula..=GAME(”StarWars”) This is what you will see…
After you have selected your hero, the game begins. Another screen shot…
You can only play the game once. To play again - exit OOo Calc and the quickstarter before restarting.

Using Names as constants
September 15th, 2005
There are many mathematical and statistical constants in use that are needed in spreadsheets. For OpenOffice Calc, only PI has been hardwired as a function call - PI()
Using defined names is a quick and easy way to define constants in your spreadsheet that will also make your formulae more legible and maintainable. There will also be no need to have hidden sheets where the constants are defined. In this example, we will define Euler’s constant - e
Open the Define Names dialog as shown below.
Instead of assigning/associating the name with a particular cell, assign a fixed value as shown below. Exit the dialog
The named constant can now be used in formulae as shown below. Note that Names defined in this way do not appear in the name box - which is just above the cells area on the left.

Listing Cell Notes
September 14th, 2005
Here is a simple macro that creates a new sheet in the Calc document with a listing of all the notes (comments) found.
Notes can be added to any cell with Insert - Note - see below.
The Basic code for gathering all of these notes and adding them to a new sheet is given below. Items in the listing I’d like to draw your attention to..
Creating new sheets with the insertNewByName method.
The PrintableAddressOfCell and ColumnNumberToString routines convert row and column cell offsets to human readable notation - and were written by Andrew Pitonyak.
The notes (annotations) for each sheet are traversed using a For loop in the exact same way as the sheets of the document.
Sub AddCommentSheet
Dim oSheets, oSheet Dim oRange, oCell Dim oAnnotations, oNote Dim i As Integer Dim j As Integer
oSheets = ThisComponent.Sheets
oSheets.insertNewByName (”Comments”, oSheets.getCOunt())
oSheet = oSheets.getByName(”Comments”)
oRange = oSheet.getCellRangeByName(”B1:C1″) oRange.merge(True)
oCell = oSheet.getCellByPosition(1,0) oCell.setString(”Comment listing”) oCell.CellBackColor = 16764057 oCell.HoriJustify = com.sun.star.table.CellHoriJustify.CENTER
oCell = oSheet.getCellByPosition(1,1) oCell.setString(”Created on …” & Now())
oCell = oSheet.getCellByPosition(1,3) oCell.setString(”Sheet”) oCell.CellBackColor = 16764057 oCell = oSheet.getCellByPosition(2,3) oCell.setString(”Cell”) oCell.CellBackColor = 16764057 oCell = oSheet.getCellByPosition(3,3) oCell.setString(”Note”) oCell.CellBackColor = 16764057
CurRow = 4 For j = 0 To oSheets.getCount()-1 oSheet2 = oSheets.getByIndex(j) oAnnotations = oSheet2.getAnnotations()
For i = 0 To oAnnotations.getCount()-1 oNote = oAnnotations.getByIndex(i) oCell = oSheet.getCellByPosition(1,CurRow+i) oCell.setString(oSheet2.Name) oCell = oSheet.getCellByPosition(2,CurRow+i) oCell.setString(PrintableAddressOfCell(oNote.getParent()) oCell = oSheet.getCellByPosition(3,CurRow+i) oCell.setString(oNote.getString()) Next CurRow = CurRow + i Next
End Sub
Function PrintableAddressOfCell(oCell) As String If IsNull(oCell) OR IsEmpty(oCell) Then PrintableAddressOfCell = “Unknown” Else PrintableAddressOfCell = ColumnNumberToString(oCell.CellAddress.Column) &_ Cstr(oCell.CellAddress.Row+1) End If End Function
Function ColumnNumberToString(ByVal nColumn As Long) As String Dim s As String Do While nColumn >= 0 s = Chr$(65 + (nColumn MOD 26)) & s nColumn = nColumn \ 26 - 1 Loop ColumnNumberToString = s End Function
The newly created comment sheet is shown below.
