to_base(val, base, opts \\ [as_list: false])
(function) # ↑

Specs:

Convert a value in decimal base (val) to an arbitrary base. If the :as_list option is true, the resulting value in base base will be returned as a list of digits.

Examples

iex> 35 |> Convertat.to_base(36)
"z"

iex> 11 |> Convertat.to_base(["a", "b"])
"babb"

iex> 6 |> Convertat.to_base(["foo", "bar"], as_list: true)
["bar", "bar", "foo"]

iex> 10 |> Convertat.to_base(["↓", "↑"])
"↑↓↑↓"
