A crate and an app to convert any integer from one numeral system to another.

Two numeral systems must be defined : one for the input number and one for the output. Any integer (of any length) can then be converted from one system to the other and vice-versa. This library uses an extension of double dabble algorithm (and reverse double dabble) to convert numbers. Binary is used as a pivot radix. It was named after french singer (and also mathematician) Boby Lapointe who invented the Bibi-binary system in 1968.

Example : using crate

```rust extern crate bibicode;

let dec = bibicode::NumeralSystem::new(vec!(vec!("0", "1", "2", "3", "4", "5", "6", "7", "8", "9"))).unwrap(); let bibi = bibicode::NumeralSystem::new(vec!(vec!("HO", "HA", "HE", "HI", "BO", "BA", "BE", "BI", "KO", "KA", "KE", "KI", "DO", "DA", "DE", "DI"))).unwrap(); let coder = bibicode::BibiCoder::new(dec, bibi); let test = coder.swap("2000").unwrap(); assert_eq!(test, "BIDAHO");

let bibi = bibicode::NumeralSystem::new(vec!(vec!("H", "B", "K", "D"), vec!("O", "A", "E", "I"))).unwrap(); let dec = bibicode::NumeralSystem::new(vec!(vec!("0", "1", "2", "3", "4", "5", "6", "7", "8", "9"))).unwrap(); let coder = bibicode::BibiCoder::new(dec, bibi); let test = coder.swap("2000").unwrap(); assert_eq!(test, "BIDAHO"); ```

Example : using application

```shell $ bibicode 1111111111111111 -f bin -t hex ffff

$ bibicode ffff -t bin -f hex 1111111111111111

$ bibicode ffffffffffffffffffffffffffffffff -t dec -f hex 340282366920938463463374607431768211455

$ bibicode 340282366920938463463374607431768211455 -f dec -t hex ffffffffffffffffffffffffffffffff
