Cardinalities

• CARDINALITY_ONE

  Matches v = 0 and i % 10 = 1 and i % 100 != 11 or f % 10 = 1 and f % 100 != 11

  Example Integers: 1, 21, 31, 41, 51, 61, 71, 81, 101, 1001, …

  Example Decimals: 0.1, 1.1, 2.1, 3.1, 4.1, 5.1, 6.1, 7.1, 10.1, 100.1, 1000.1, …

• CARDINALITY_FEW

  Matches v = 0 and i % 10 = 2..4 and i % 100 != 12..14 or f % 10 = 2..4 and f % 100 != 12..14

  Example Integers: 2, 4, 22, 24, 32, 34, 42, 44, 52, 54, 62, 102, 1002, …

• CARDINALITY_OTHER

  Matches all other values

  Example Integers: 0, 5, 19, 100, 1000, 10000, 100000, 1000000, …

  Example Decimals: 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 2.7, 10.0, 100.0, 1000.0, 10000.0, 100000.0, 1000000.0, …

Cardinality example

This localized strings file selects the localized form of “day” for a delivery estimate. Raw numbers choose the CLDR category; values formatted with the JDK NumberFormat are interpolated for display.

Sample localized strings file

{
  "Delivery.LeadTime": {
    "commentary": "Estimated delivery time, expressed in days.",
    "translation": "{{leadTime}}",
    "placeholders": {
      "leadTime": {
        "value": "dayCount",
        "translations": {
          "CARDINALITY_ONE": "{{formattedDayCount}} dan",
          "CARDINALITY_FEW": "{{formattedDayCount}} dana",
          "CARDINALITY_OTHER": "{{formattedDayCount}} dana"
        }
      }
    }
  }
}

Usage and expected results

The Java code passes each raw number for cardinality selection and formats its display value separately with NumberFormat. The exact-tag 1,000,000 assertion records JDK 26 output; older JDK locale data can differ.

Locale locale = Locale.forLanguageTag("sr-Latn");

Strings strings = Strings.withFallbackLocale(locale)
  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))
  .localeSupplier((matcher) -> matcher.bestMatchFor(locale))
  .build();

NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);

// Raw numbers select language forms; NumberFormat produces the display values

// CARDINALITY_ONE
Number oneDayCount = 1;
String oneFormattedDayCount = numberFormat.format(oneDayCount);

// Expected: 1 dan
assertEquals(oneFormattedDayCount + " dan", strings.get(
  "Delivery.LeadTime", Map.of("dayCount", oneDayCount, "formattedDayCount", oneFormattedDayCount)
));

// CARDINALITY_FEW
Number fewDayCount = 2;
String fewFormattedDayCount = numberFormat.format(fewDayCount);

// Expected: 2 dana
assertEquals(fewFormattedDayCount + " dana", strings.get(
  "Delivery.LeadTime", Map.of("dayCount", fewDayCount, "formattedDayCount", fewFormattedDayCount)
));

// CARDINALITY_OTHER
Number otherDayCount = 0;
String otherFormattedDayCount = numberFormat.format(otherDayCount);

// Expected: 0 dana
assertEquals(otherFormattedDayCount + " dana", strings.get(
  "Delivery.LeadTime", Map.of("dayCount", otherDayCount, "formattedDayCount", otherFormattedDayCount)
));

// Exact-tag formatting sample
Number localeProfileDayCount = 1_000_000;
String localeProfileFormattedDayCount = numberFormat.format(localeProfileDayCount);

assertEquals("1.000.000", localeProfileFormattedDayCount);

assertEquals(Cardinality.OTHER, Cardinality.forNumber(localeProfileDayCount, locale));

// Expected: 1.000.000 dana
assertEquals(localeProfileFormattedDayCount + " dana", strings.get(
  "Delivery.LeadTime",
  Map.of("dayCount", localeProfileDayCount, "formattedDayCount", localeProfileFormattedDayCount)
));

Cardinality Ranges

These are CLDR's explicit range mappings. For any start/end pair not listed, Cardinality.forRange(...) falls back to the ending cardinality.

• CARDINALITY_ONE - CARDINALITY_ONE

  Matches CARDINALITY_ONE

• CARDINALITY_ONE - CARDINALITY_FEW

  Matches CARDINALITY_FEW

• CARDINALITY_ONE - CARDINALITY_OTHER

  Matches CARDINALITY_OTHER

• CARDINALITY_FEW - CARDINALITY_ONE

  Matches CARDINALITY_ONE

• CARDINALITY_FEW - CARDINALITY_FEW

  Matches CARDINALITY_FEW

• CARDINALITY_FEW - CARDINALITY_OTHER

  Matches CARDINALITY_OTHER

• CARDINALITY_OTHER - CARDINALITY_ONE

  Matches CARDINALITY_ONE

• CARDINALITY_OTHER - CARDINALITY_FEW

  Matches CARDINALITY_FEW

• CARDINALITY_OTHER - CARDINALITY_OTHER

  Matches CARDINALITY_OTHER

Cardinality range example

The start and end cardinalities select the locale's CLDR range result. The selected form wraps a separately formatted display range.

Sample localized strings file

{
  "Delivery.Window": {
    "commentary": "Estimated delivery window, expressed as a range of days.",
    "translation": "{{window}}",
    "placeholders": {
      "window": {
        "range": {
          "start": "minDays",
          "end": "maxDays"
        },
        "translations": {
          "CARDINALITY_ONE": "{{formattedDayRange}} dan",
          "CARDINALITY_FEW": "{{formattedDayRange}} dana",
          "CARDINALITY_OTHER": "{{formattedDayRange}} dana"
        }
      }
    }
  }
}

Usage and expected results

The Java code passes raw range endpoints for selection. Because NumberFormat formats one number at a time, it formats both endpoints separately and joins them for display; choose range punctuation appropriate to your application.

Locale locale = Locale.forLanguageTag("sr-Latn");

Strings strings = Strings.withFallbackLocale(locale)
  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))
  .localeSupplier((matcher) -> matcher.bestMatchFor(locale))
  .build();

NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);

// Raw numbers select language forms; NumberFormat produces the display values

// CARDINALITY_ONE range
Number minDays = 1;
String formattedMinDays = numberFormat.format(minDays);
Number maxDays = 21;
String formattedMaxDays = numberFormat.format(maxDays);
String formattedDayRange = formattedMinDays + "-" + formattedMaxDays;

assertEquals(Cardinality.ONE, Cardinality.forRange(
  Cardinality.forNumber(minDays, locale),
  Cardinality.forNumber(maxDays, locale),
  locale
));

// Expected: 1-21 dan
assertEquals(formattedDayRange + " dan", strings.get(
  "Delivery.Window",
  Map.of("minDays", minDays, "maxDays", maxDays, "formattedDayRange", formattedDayRange)
));

Ordinalities

All ordinal numbers use ORDINALITY_OTHER; no value selects a different form.

Example: Skrenite u 2. desno..

Addendum: Language Form Rules

The language form expressions above are specified by Unicode Technical Standard #35 and use the following notation:

• n absolute value of the source number (integer and decimals)
• i integer digits of n
• v number of visible fraction digits in n, with trailing zeros
• w number of visible fraction digits in n, without trailing zeros
• f visible fractional digits in n, with trailing zeros
• t visible fractional digits in n, without trailing zeros
• c/e compact decimal exponent operands used by some CLDR compact-number rules
