Thanks and congratulations to Németh László for solving the problem for words presentation of numbers in Calc and Writer. However, there are two errors in the Polish version of this algorithm. This applies to the number 3 and numbers with the digit 3 in the last position, (except for the combination 13) in the form of an ordinal number in feminine and neuter form. The feminine form now is: "trzeca" should be "trzecia" The neuter form now is "trzece", it should be "trzecie".
Hello Jerzy, not sure if bugzilla is for libnumbertext, but https://github.com/Numbertext/libnumbertext/issues
@Jerzy & Raal: many thanks for the bug report and QA! I plan to fix the issue soon, and update libnumbertext in LibreOffice. (You don't need to repeat the bug report in gitHub, I've assigned to myself to this bug report.)
