[libreoffice-users] Re: Using and Formatting Logical Functions in Calc

Hi,

Like any other programming language Calc can nest functions as far as 
the data types of the incoming parameters match the data types of the 
nested function results. The details are mostly the same as with any 
other spreadsheet program of the past 30 years with the only exception 
that there is no boolean data type. TRUE equals 1, FALSE equals 0 
without any conversion.

A Calc cell can have a number, text, blank and error. All constants are 
number or text, a formula may return number, text or error.

=FUNCTION(number ; text ; range ; vector )

*should* be nested like this:

> =FUNCTION( function_number(x) ; function_text(x) ; function_range(x) ; function_vector(x) )

[a vector is a range made of a single row or column. Sometimes this 
shape is required]

The function wizard can be of great help when composing nested functions.

Personally, I avoid deeply nested function calls. They are much harder 
to maintain and debug.

Apart from the functions of category "Text" all spreadsheet functions 
return numbers.
Functions of category "Spreadsheet" return references to other cells.

Base is not a database. Please feel free to use your preferred 
connectable database and connect it with a Base document in order to use 
it in the context of this office suite. I do so successfully since many 
years (OOo 1.1) within the limits of this very simple tool set. A decent 
database is not exclusively bound to one particular front-end.

Hope that helps,
A.S.
