Configure your own language

Each language has its own unique grammar exceptions. You can create your own language.json file in the folder "i18n" and give writtenNumber support for it. I don't think the current scheme and logic cover all the cases, but may be cover some.

The following parameters have been used for the currently available languages:

Language parameters

Parameter	Type	Description	Examples
useLongScale	boolean	Indicates if it uses long or short scale.	This differs the meaning of the words billion, trillion and so on.
baseSeparator	string	Separates the base cardinal numbers.	29 -> twenty-eight. Spanish uses the connector " y "
unitSeparator	string	Separates the units from the last base cardinal numbers.	1234 -> one thousand two hundred and thirty-four
allSeparator	string	Separates all cardinals, not only the last one.	1125 -> ألف ومائة وخمسة وعشرون
base	Object	Base cardinals numbers. Numbers that have unique names and are used to build others.
alternativeBase	Object	Alternative versions of base cardinals numbers for usage with specific units. These bases will be treated as an extension for the default base.	"alternativeBase": { "feminine": {"1":"одна","2":"дві"} }
units	Array	A list of number units (string or Object). Gives support to singular, dual an plural units. Check the Object parameters below.
unitExceptions	Object	Sometimes grammar exceptions affect the base cardinal joined to the unit. You can set specific exceptions to any base cardinal number.	Converting 1232000 in Spanish: Without Exception (Wrong): -> uno millón doscientos treinta y dos mil With Exception: -> un millón doscientos treinta y dos mil

Units parameters

A unit can be:

• A simple string. e.g. "hundred"
