# All Your Base
|
|
|
|
Welcome to All Your Base on Exercism's Elixir Track.
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
|
|
|
## Instructions
|
|
|
|
Convert a number, represented as a sequence of digits in one base, to any other base.
|
|
|
|
Implement general base conversion.
|
|
Given a number in base **a**, represented as a sequence of digits, convert it to base **b**.
|
|
|
|
## Note
|
|
|
|
- Try to implement the conversion yourself.
|
|
Do not use something else to perform the conversion for you.
|
|
|
|
## About [Positional Notation][positional-notation]
|
|
|
|
In positional notation, a number in base **b** can be understood as a linear combination of powers of **b**.
|
|
|
|
The number 42, _in base 10_, means:
|
|
|
|
`(4 * 10^1) + (2 * 10^0)`
|
|
|
|
The number 101010, _in base 2_, means:
|
|
|
|
`(1 * 2^5) + (0 * 2^4) + (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (0 * 2^0)`
|
|
|
|
The number 1120, _in base 3_, means:
|
|
|
|
`(1 * 3^3) + (1 * 3^2) + (2 * 3^1) + (0 * 3^0)`
|
|
|
|
I think you got the idea!
|
|
|
|
_Yes. Those three numbers above are exactly the same. Congratulations!_
