Subject: Data Type Specification and Conversion like in FORTRESS
A major disadvantage of every spreadsheet application is the lack of coding capabilities to explicitly state the type of the values. This *major design flaw* of spreadsheets makes them very error prone when intermingling various data formats. I really miss something like the new FORTRESS (see http://fortress.sunsource.net/). In my primary work, I am overseeing 100+ employees working extensively with worksheets. Unfortunately, there were often situations where 2 currencies were used, providing a perfect milieu for conversion errors, e.g. 1,000,000 RON equals approx. 300,000 Euro, BUT adding 1,000,000 or 300,000 makes a great difference (of 700,000 RON or Euro). The globalisation trend will only foster this development. The killer feature that will differentiate spreadsheets from the '70-'80s from modern concepts would allow the user to specify the type of the data, e.g.: A1: 30 m A2: 125 cm A3: 86 inch A4: = SUM(A1:A3) => implicit conversions are done 2nd example: A1: 1.2 M Euro A2: 0.67 M $ A3: =SUM(A1:A2) => implicit conversion using a pre-specified conversion rule As this feature will differentiate the flawed concepts of the past from the modern views, I hope that it gets implemented in the ODF specification. Kind regards, Leonard Mada
