Cardinalities

• CARDINALITY_ZERO

  Matches n = 0

  Example Integers: 0

  Example Decimals: 0.0, 0.00, 0.000, 0.0000

• CARDINALITY_ONE

  Matches n = 1

  Example Integers: 1

  Example Decimals: 1.0, 1.00, 1.000, 1.0000

• CARDINALITY_OTHER

  Matches all other values

  Example Integers: 2, 17, 100, 1000, 10000, 100000, 1000000, …

  Example Decimals: 0.1, 0.9, 1.1, 1.7, 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 cv 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("cv");

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_ZERO
Number zeroCardinalityValue = 0;
String zeroFormattedCardinalityValue = numberFormat.format(zeroCardinalityValue);

assertEquals(Cardinality.ZERO, Cardinality.forNumber(zeroCardinalityValue, locale));

assertEquals("Пан улми ҫук.", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", zeroCardinalityValue,
    "formattedCardinalityValue", zeroFormattedCardinalityValue
  )
));

// CARDINALITY_ONE
Number oneCardinalityValue = 1;
String oneFormattedCardinalityValue = numberFormat.format(oneCardinalityValue);

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

// Expected: 1 пан улми пур. Ӑна илесшӗн-и?
assertEquals(oneFormattedCardinalityValue + " пан улми пур. Ӑна илесшӗн-и?", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", oneCardinalityValue,
    "formattedCardinalityValue", oneFormattedCardinalityValue
  )
));

// CARDINALITY_OTHER
Number otherCardinalityValue = 2;
String otherFormattedCardinalityValue = numberFormat.format(otherCardinalityValue);

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

// Expected: 2 пан улми пур. Вӗсене илесшӗн-и?
assertEquals(otherFormattedCardinalityValue + " пан улми пур. Вӗсене илесшӗн-и?", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", otherCardinalityValue,
    "formattedCardinalityValue", otherFormattedCardinalityValue
  )
));

Cardinality Ranges

No explicit CLDR cardinality-range mapping is defined for this language. Cardinality.forRange(...) therefore falls back to the ending cardinality for every range.

Ordinalities

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

Example: 2-мӗш пан улми выртать..

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
