Which formats should we consider?

36.00
36,00
36
36 zł
36,00 PLN
any else?

I think that format is not such important, when we will use regex.

There is a problem with comma vs. dot as this is locale (language) dependant. What's more is that users often tend to paste formats different from their locale and this has to be handled in some meaningful way.

If we go for pure JavaScript solution then user may see changes to his input in the realtime - and I don't think we should bother backend with such details.

We can detect which format (comma/dot) user has in mind by looking how those symbols show up in the number. For example in English 1,499.99$ is a valid number. In Polish this may be written as 1 499,99zł.

One way to to handle this is to throw away non-digits and deduct which sign is used for decimal part based on number of decimal digits.
