Are you in need of Fuzzy math. I do not mean the political rhetoric, but rather the mathematical concept of fuzzy logic and fuzzy math.
Now you can calculate with fuzzy math in OpenOffice.org Calc spreadsheets, thanks to the new InrecoLAN FuzzyMath component.
The component allows to use uncertain or approximate values in OpenOffice.org Calc. It means you can perform ordinary arithmetic operations and use ordinary mathematical and financial functions with uncertain values as if they are standard, or crisp, numbers. The component allows you to create and edit fuzzy numbers, use fuzzy numbers in formulas. You can also display the graphs from the fuzzy numbers and results of calculations.
Fuzzy math has strong mathematical basis. This component enhances all mathematical and financial OpenOffice.org Calc functions for which fuzziness might be reasonable.
