@macchiati The proposed algorithm doesn't seem to work correctly for the example data in the spec.

I assume that the correct localized string should be "12 mille $" not "12 $ mille"

[macchiati]

I agree with you that "12 $ mille" feels very odd, with the $ between parts of a number.

I have trouble understanding the sentence as written. Do you mean something like the following?

When there is no data available for <currencyFormatLength type=X>, use the following process (with the example currency value <20034.56, EUR>:

• Look at the corresponding <decimalFormatLength type=X> pattern
  • if that pattern is "0" (which means use normal formatting), use <currencyFormat type="standard"> to format, and exit.
• otherwise:
  • format the numeric value of the currency value with <decimalFormatLength type=X>, such as 20034.56 → "20 M"
  • get the localized symbol for the pattern, eg EUR → "€"
  • pick the pattern (plain or alt="alphaNextToNumber") based on the localized symbol and the formatted numeric value.
  • replace the numeric part of the pattern by the formatted numeric value and the currency symbol character (¤) by the localized symbol, such as "#,##0.00¤" → "20 M€"

No, that's not the algorithm I understood from the ticket and our CLDR-WG discussion. The algorithm I understood was:

• otherwise:
  • Adjust the numeric value according to compact currency rules. For example, 20034.56 EUR becomes 20.03456c3, and after rounding becomes 20c3
  • Format the mantissa using <currencyFormat type="standard">, as in "20€"
  • Substitute that value into the correct compact currency form (the one corresponding to "c3"), as in "20€ mille"

However, maybe your algorithm is better; at least it works in French, and my algorithm doesn't :)

I think we need to take this back to Design

Let's hold off on this for now; we need to work in the decimals and the spacing. We can also test against the data for the locales we have.
