LibreOffice 24.8 Help
You can apply user-defined functions in LibreOffice Calc in the following ways:
You can define your own functions using the Basic-IDE. This method requires a basic knowledge of programming.
You can program functions as add-ins. This method requires an advanced knowledge of programming.
Choose
.You will now see the Basic IDE.
In the Object Catalog window, double-click on the module where you want to store your macro.
Enter the function code. In this example, we define a VOL(a; b; c) function that calculates the volume of a rectangular solid with side lengths a, b and c:
Function VOL(a, b, c)
VOL = a*b*c
End Function
Close the Basic-IDE window.
Your function is automatically saved in the selected module and is now available. If you apply the function in a Calc document that is to be used on another computer, you can copy the function to the Calc document as described in the next section.
In stage 2 of "Defining A Function Using LibreOffice Basic", in the Macro dialog you clicked on Edit . As the default, in the Macro from field the My Macros - Standard - Module1 module is selected. The Standard library resides locally in your user directory.
If you want to copy the user-defined function to a Calc document:
Choose
.In the Macro from field select My Macros - Standard - Module1 and click Edit.
In the Basic-IDE, select the source of your user-defined function and copy it to the clipboard.
Close the Basic-IDE.
Choose
.In the Macro from field select (Name of the Calc document) - Standard - Module1. Click Edit.
Paste the clipboard contents in the Basic-IDE of the document.
Once you have defined the function VOL(a; b; c) in the Basic-IDE, you can apply it the same way as the built-in functions of LibreOffice Calc.
Open a Calc document and enter numbers for the function parameters a, b and c in cells A1, B1, and C1.
Set the cursor in another cell and enter the following:
=VOL(A1;B1;C1)
The function is evaluated and you will see the result in the selected cell.
