Hello,
CompactNumberFormat has been added since JDK 12 to support compact
number formatting, such as 10_000 being formatted as "10K." [1] It works
fine for English, however, not for other languages that take plural
forms in formatted number prefixes/suffixes. In order to fix this, I
filed the following CSR to extend the current CompactNumberFormat spec:
https://bugs.openjdk.java.net/browse/JDK-8232633
It basically accommodates the plural prefix/suffix forms into the
existing compact patterns array, so that the existing compact number
format works compatibly. The plural rules are solely based on the CLDR's
plural language rules [2]
Here is the implementation of the CSR:
https://cr.openjdk.java.net/~naoto/8222756/webrev.00/
Please review the CSR as well as its implementation.
