Plural forms in Czech

[Petr Kadlec]

Hi!

I have noticed that GNU gettext contains the following formula to determine 
the plural type to be used for Czech (cs):
plural=(n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || 
n%100>=20) ? 1 : 2);

(It is mentioned in the documentation and used in 
gettext-tools/src/plural-table.c.)

While this is not exactly incorrect, it is not really used in todays 
language. Nowadays, we have practically abandoned the convention of 
singular-like endings for 101, 201, ..., 1001, 1101, ... (Similarly for 
102, 103, 104, 202, ...) Almost any today speaker would use the following rule:
plural=(n==1) ? 0 : (n>=2 && n<=4) ? 1 : 2;
(Which is identical to Slovak.)

In case there is some czech-speaking person who is not sure whether this is 
"officially correct", please see this FAQ item at the website of the 
Institute of the Czech Language: http://www.ujc.cas.cz/poradna/odpo.html#dveste

With regards,
Petr Kadlec
