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 br 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("br");

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 cʼhi
assertEquals(oneFormattedCardinalityValue + " cʼhi", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", oneCardinalityValue,
    "formattedCardinalityValue", oneFormattedCardinalityValue
  )
));

// CARDINALITY_TWO
Number twoCardinalityValue = 2;
String twoFormattedCardinalityValue = numberFormat.format(twoCardinalityValue);

assertEquals(Cardinality.TWO, Cardinality.forNumber(twoCardinalityValue, locale));

// Expected: 2 gi
assertEquals(twoFormattedCardinalityValue + " gi", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", twoCardinalityValue,
    "formattedCardinalityValue", twoFormattedCardinalityValue
  )
));

// CARDINALITY_FEW
Number fewCardinalityValue = 3;
String fewFormattedCardinalityValue = numberFormat.format(fewCardinalityValue);

assertEquals(Cardinality.FEW, Cardinality.forNumber(fewCardinalityValue, locale));

// Expected: 3 cʼhi-error
assertEquals(fewFormattedCardinalityValue + " cʼhi-error", strings.get(
  "Cardinality.MinimalPair",
  Map.of(
    "cardinalityValue", fewCardinalityValue,
    "formattedCardinalityValue", fewFormattedCardinalityValue
  )
));

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

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

// Expected: 1<NBSP>000<NBSP>000 a chas
assertEquals(manyFormattedCardinalityValue + " a chas", 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 ki
assertEquals(otherFormattedCardinalityValue + " ki", 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.

Cardinality range example

Because CLDR defines no explicit range mapping for this locale, the ending cardinality selects the result. The selected form wraps a separately formatted display range.

{
  "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}} deiz",
          "CARDINALITY_TWO": "{{formattedDayRange}} zeiz",
          "CARDINALITY_FEW": "{{formattedDayRange}} deiz",
          "CARDINALITY_MANY": "{{formattedDayRange}} a zeizioù",
          "CARDINALITY_OTHER": "{{formattedDayRange}} deiz"
        }
      }
    }
  }
}

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("br");

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_OTHER range (ending-cardinality fallback)
Number minDays = 0;
String formattedMinDays = numberFormat.format(minDays);
Number maxDays = new java.math.BigDecimal("0.9");
NumberFormat maxDaysFormat = NumberFormat.getNumberInstance(locale);
maxDaysFormat.setMinimumFractionDigits(1);
maxDaysFormat.setMaximumFractionDigits(1);
String formattedMaxDays = maxDaysFormat.format(maxDays);
String formattedDayRange = formattedMinDays + "-" + formattedMaxDays;

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

// Expected: 0-0,9 deiz
assertEquals(formattedDayRange + " deiz", 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: 2vet.

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
