Picho,
In my opinion, forget to do it with globalization.
I know that it has in 2 languages this exceptions for let say 98 in words
(in English Words)
What is in a lot of languages like English: Ninty eight
In German/Dutch: Eight and ninty
In French/French: Four times twenty and ten eight
Belgian/French like the English
I once saw a link given by Peter Huang about VB6, it is so simple that it
should be made in C# just changing a little bit in my opinion to use the
words.
