Type declaration

  • integer: (
        ctx: MessageFunctionContext,
        exprOpt: Record<string, unknown>,
        operand?: unknown,
    ) => MessageNumber

    Supports formatting and selection as defined in LDML 47 for the :integer function.

    The operand must be a number, BigInt, or string representing a JSON number, or an object wrapping such a value, with a valueOf() accessor and an optional options object.

  • number: (
        ctx: MessageFunctionContext,
        exprOpt: Record<string, unknown>,
        operand?: unknown,
    ) => MessageNumber

    Supports formatting and selection as defined in LDML 47 for the :number function.

    The operand must be a number, BigInt, or string representing a JSON number, or an object wrapping such a value, with a valueOf() accessor and an optional options object.

  • string: (
        ctx: Pick<MessageFunctionContext, "dir" | "locales" | "source">,
        _options: Record<string, unknown>,
        operand?: unknown,
    ) => MessageString

    Supports formatting and selection as defined in LDML 47 for the :string function.

    The operand must be a stringifiable value. An undefined value is resolved as an empty string.
