NumWord
NumWord deals with the number words in natural languages. You can enter a sequence of digits, and the program will write the number word as it is spelled in the desired language. Likewise, a number word can be entered and the program will write the corresponding number as a sequence of digits.
Furthermore, the module maps numbers to a few calendar-related sets of words in natural languages:
- 1..7 to weekday names (Monday ... Sunday) and their abbreviations
- 1..12 to month names (January ... December)
- 1..4 to words for seasons (spring, summer, autumn, winter)

Problems
- For right-to-left languages (Arabic) the lists are not always displayed properly.
- Testing is rather difficult if you are not a native speaker of the language.
- Some languages declinate words for small numbers (1,2,3). The current implementation doesn't attempt to handle variations for gender, numerus and case properly, except for singular/plural of million, milliard, billion etc. Dual is also not yet supported.
- It is an interesting fact that the numbering schemes in most languages use powers of 1000, but there are exceptions where special words for (powers of) 10000 are used (Klingon, SinoSpeller).
- For the languages based on powers of 1000, a fixed set of Latin prefixes is used for numbers >= 1 million (c.f. BaseSpeller.wordN000). For some languages these prefixes must be modified (cyrillic character set, c -> k in German).
- Some languages still use different number word sets for living entities, cattle, money etc. There is currently no attempt to handle these variations.
