Resolve Plural Category

localization.plural_category_resolve

ProductionEngine wrapper (Class A)Deterministicstrictinstantv1.0.0

No network

Overview

You send a BCP 47 locale, a decimal string, and CARDINAL or ORDINAL. We return ZERO, ONE, TWO, FEW, MANY or OTHER together with the visible fraction-digit counts that CLDR uses, so 1 and 1.0 can differ. Exponent notation is refused. We do not format the number or compile custom plural rules. A successful call costs 1 execution credit.

CLDR plural operands distinguish 1 from 1.0. A model cannot prove the category from the locale tag and the decimal string alone.

Reliability

Same locale, same decimal string, same type, same ICU/CLDR versions, same answer. LOCALE_INVALID — trigger: the locale is POSIX or ill-formed; retryable: no; next: send a hyphenated BCP 47 tag. NUMBER_FORMAT_INVALID — trigger: exponent notation, empty, or a non-decimal string; retryable: no; next: send 1 or 1.0, not 1e0.

Context footprint

One locale and one number in. A successful call costs 1 execution credit.

When to use it

When you hold a locale and a decimal string and need the CLDR plural bucket.

When you want the formatted phrase, or a locale picked from Accept-Language.

Scope

Note

Returns the CLDR cardinal or ordinal plural category for one locale and one decimal string.

Non-goals

Does not format the number or the message
Does not resolve plural ranges
Does not compile caller-supplied plural rules
