Hi guys!

I’m super new to Elixir, and my English can be a little bad, so I’m sorry about that.

Well, I’m here to get some advice on my code, it works well, but I don’t know if there’s anything I can do to make it more like the “Elixir way of things”. So if anyone can rate it and give me some tips

Ps: The challenge is only for numbers up to 3000

Here’s the code

```
defmodule Converter do
@one "I"
@five "V"
@ten "X"
@fifty "L"
@onehundread "C"
@fivehundread "D"
@onethousand "M"
def to_roman_number(number,roman_number \\ "",n \\ 3)
def to_roman_number(number,roman_number,_n) when number == 4,do: roman_number<>@one<>@five
def to_roman_number(number,roman_number,_n) when div(number,10) == 4 do
roman_conversion = roman_number<>@ten<>@fifty
rest = rem(number,10)
to_roman_number(rest,roman_conversion,0)
end
def to_roman_number(number,roman_number,_n) when div(number,100) == 4 do
roman_conversion = roman_number<>@onehundread<>@fivehundread
rest = rem(number,100)
to_roman_number(rest,roman_conversion,1)
end
def to_roman_number(number,roman_number,_n) when number == 5, do: roman_number<>@five
def to_roman_number(number,roman_number,_n) when div(number,10) == 5 do
roman_conversion = roman_number<>@fifty
rest = rem(number,10)
to_roman_number(rest,roman_conversion,0)
end
def to_roman_number(number,roman_number,_n) when div(number,100) == 5 do
roman_conversion = roman_number<>@fivehundread
rest = rem(number,100)
to_roman_number(rest,roman_conversion,1)
end
def to_roman_number(number,roman_number,_n) when number == 9,do: roman_number<>@one<>@ten
def to_roman_number(number,roman_number,_n) when div(number,10) == 9 do
roman_conversion = roman_number<>@ten<>@onehundread
rest = rem(number,10)
to_roman_number(rest,roman_conversion,0)
end
def to_roman_number(number,roman_number,_n) when div(number,100) == 9 do
roman_conversion = roman_number<>@onehundread<>@onethousand
rest = rem(number,100)
to_roman_number(rest,roman_conversion,1)
end
def to_roman_number(number,roman_number,n) do
base = trunc(:math.pow(10,n))
quotient = div(number,base)
rest = rem(number,base)
cond do
n == 3 ->
roman_conversion = roman_number<>String.duplicate(@onethousand,quotient)
to_roman_number(rest,roman_conversion,n-1)
n == 2 ->
roman_conversion = roman_number<>String.duplicate(@onehundread,quotient)
to_roman_number(rest,roman_conversion,n-1)
n == 1 ->
roman_conversion = roman_number<>String.duplicate(@ten,quotient)
to_roman_number(rest,roman_conversion,n-1)
n == 0 ->
roman_conversion = roman_number<>String.duplicate(@one,quotient)
IO.puts "The converted number is "<>roman_conversion
end
end
end
```
