This is yet another implementation of NewBase60 algorithm made for Kotlin and Java.

In a nutshell, this library will be useful if you want to implement a URL shortener, like Bitly or TinyURL, that is URL-safe and does not contain confusing character pairs, such as an uppercase letter O and 0, an uppercase letter I and 1.

Check out this article of Tantek Çelik for more information.

Examples

numberToSexagesimal(0) // "0"
numberToSexagesimal(60) // "10"
numberToSexagesimal(1337) // "NH"
numberToSexagesimal(9_223_372_036_854_775_807) // "FFD_YXvLFW7"
sexagesimalToNumber("10") // 60L
sexagesimalToNumber("NH") // 1337L
sexagesimalToNumber("NH🥺") // java.text.ParseException(errorOffset=2, detailMessage="Couldn't parse the character "🥺"")
