Constants

  • int
    CURRENCY_ACCOUNTING 
    12

    ICU Constant for accounting format; not yet widely supported by INTL library. This will be able to go away once CakePHP minimum PHP requirement is 7.4.1 or higher. See UNUM_CURRENCY_ACCOUNTING in https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/unum_8h.html

  • string
    DEFAULT_LOCALE 
    'en_US'

    Default locale

  • string
    FORMAT_CURRENCY 
    'currency'

    Format type to format as currency

  • string
    FORMAT_CURRENCY_ACCOUNTING 
    'currency_accounting'

    Format type to format as currency, accounting style (negative numbers in parentheses)

Property Summary

  • $_defaultCurrency protected static
    string|null

    Default currency used by Number::currency()

  • $_defaultCurrencyFormat protected static
    string|null

    Default currency format used by Number::currency()

  • $_formatters protected static
    array<string, array<int, mixed>>

    A list of number formatters indexed by locale and type

Method Summary

  • _setAttributes() protected static

    Set formatter attributes

  • config() public static

    Configure formatters.

  • currency() public static

    Formats a number into a currency format.

  • defaultCurrency() public static deprecated

    Getter/setter for default currency. This behavior is deprecated and will be removed in future versions of CakePHP.

  • format() public static

    Formats a number into the correct locale format

  • formatDelta() public static

    Formats a number into the correct locale format to show deltas (signed differences in value).
