type Form ¶

type Form byte

const (
	Other Form = iota
	Zero
	One
	Two
	Few
	Many
)

type Rules ¶

type Rules interface {
	// Ordinal is used to determine e.g. 0 days, 1 day, 2 days. For example,
	// for locale "en", Ordinal("2") == Many.
	Ordinal(number string) Form

	// Cardinal is used to determine e.g. 1st, 2nd, 3rd. For example,
	// for locale "en", Cardinal("3") == Few.
	Cardinal(number string) Form
}

Rules implements plural forms of a number for a given locale.

Numbers represented by a string must be formatted with the ASCII digits '0' to '9', and optionally with a single decimal point encoded as the ASCII character '.'.

If an argument is of the wrong format, or out of range of an int64, the result will be Other.
