Cardinalities

• CARDINALITY_ONE

  Matches i = 1 and v = 0

  Example Integers: 1

• CARDINALITY_MANY

  Matches e = 0 and i != 0 and i % 1000000 = 0 and v = 0 or e != 0..5

  Example Integers: 1000000, …

• CARDINALITY_OTHER

  Matches all other values

  Example Integers: 0, 2, 16, 100, 1000, 10000, 100000, …

  Example Decimals: 0.0, 1.5, 10.0, 100.0, 1000.0, 10000.0, 100000.0, 1000000.0, …

Cardinality example

This localized strings example uses complete, page-local CLDR minimal-pair patterns to demonstrate every Cardinality category defined for the locale. Minimal-pair text contrasts grammatical forms; it is language-reference data, not reusable application copy.

Source: Unicode CLDR 48.2 scn locale data.

Usage and expected results

The Java code passes each raw number for cardinality selection and formats its display value separately with NumberFormat.

Locale locale = Locale.forLanguageTag("scn");

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 oneCardinalityValue = 1;
String oneFormattedCardinalityValue = numberFormat.format(oneCardinalityValue);

assertEquals(Cardinality.ONE, Cardinality.forNumber(oneCardinalityValue, locale));

// Expected: 1 jornu
assertEquals(oneFormattedCardinalityValue + " jornu", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", oneCardinalityValue,
    "formattedCardinalityValue", oneFormattedCardinalityValue
  )
));

// CARDINALITY_MANY
Number manyCardinalityValue = 1_000_000;
String manyFormattedCardinalityValue = numberFormat.format(manyCardinalityValue);

assertEquals(Cardinality.MANY, Cardinality.forNumber(manyCardinalityValue, locale));

// Expected: 1.000.000 di jorna
assertEquals(manyFormattedCardinalityValue + " di jorna", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", manyCardinalityValue,
    "formattedCardinalityValue", manyFormattedCardinalityValue
  )
));

// CARDINALITY_OTHER
Number otherCardinalityValue = 0;
String otherFormattedCardinalityValue = numberFormat.format(otherCardinalityValue);

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

// Expected: 0 jorna
assertEquals(otherFormattedCardinalityValue + " jorna", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", otherCardinalityValue,
    "formattedCardinalityValue", otherFormattedCardinalityValue
  )
));

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_OTHER

  Matches CARDINALITY_OTHER

• CARDINALITY_OTHER - CARDINALITY_ONE

  Matches CARDINALITY_ONE

• CARDINALITY_OTHER - CARDINALITY_OTHER

  Matches CARDINALITY_OTHER

Ordinalities

• ORDINALITY_MANY

  Matches n = 11,8,80..89,800..899

  Example Integers: 8, 11, 80, 89, 800, 803

• ORDINALITY_OTHER

  Matches all other values

  Example Integers: 0, 7, 9, 10, 12, 17, 100, 1000, 10000, 100000, 1000000, …

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
