Method Detail

parseCardinal

@Nullable
public static Long parseCardinal(String text)

Parses a cardinal number from the string supplied.

Parameters:

text - string to be parsed

Returns:

parsed cardinal number; null on failure

spellCardinal

public static String spellCardinal(int num)

Returns the word for a number in some language. This method is the heart of the package. It assumes the "normal" european numbering system derived from latin. The entire number is splitted into triples of digits: hundreds, tens, and ones. These are spelled in order, joined by some morphemes like "and", and "s" for plural. The words for ones, tens, for 10..19 and sometimes for the hundreds are stored in language specific arrays.

Parameters:

number - a sequence of digit characters, maybe interspersed with non-digits (spaces, punctuation).

Returns:

number word

@Nullable
public static Long parseOrdinal(String string)

spellOrdinal

public static String spellOrdinal(int ordinal)

isOrdinal
