Functions

func Decode 

func Decode(bucket int64) (float64, float64, bool)

Decode is the inverse operation of Encode. Decode returns latitude, longitude, and whether or not they are both represented precisely as float64 types.

func Encode 

func Encode(latitude, longitude float64, validate bool, precision int) int64

Encode generates a geozip bucket id for a given latitude and longitude. Argument validate is true if a validation is to be performed. Precision is a number in the range of [0, 18] such that 0 gives lowest precision (000000000000000000) and 18 gives the most precise bucket id.

func Valid 

func Valid(latitude, longitude float64) bool

Valid returns true if latitude is in the range of [-90, 90] and longtitude is in the range of [-180, 180].
