Comment (by Michal Čihař):
Replying to [comment:50 Michal Hozza]:
> This is actually not true. `n%1 != 0` for decimal numbers. I believe
Czech has a special plural form for decimal numbers, similarly to Slovak,
so the formula is correct.
Yes, but the Gettext logic is integer only, so it cannot evaluate
decimals. So while it's theoretically correct, it doesn't make sense with
Gettext where the expression is evaluated as integers because for every
integer, `n%1 == 0`.
This is how it ends up being evaluated:
{{{
>>> from gettext import c2py
>>> c2py('n%1')(1.5)
0
}}}
But this is really off-topic here, this is just special case where plural
rules can be different, there are languages where the differences are
intentional depending on scope of the translation and this is now handled
properly by Django.
