# 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](https://en.wikipedia.org/wiki/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!*
