how do I round off a given number to the nearest multiple of 10 in elixir

It’s probably like rounding the tenth of the value… and multiply by 10.

Well, you didn’t specified the rounding method, so I assume that any will do:

def round10(n) when rem(n, 10) < 6, do: n - rem(n, 10)
def round10(n), do: n + (10 - rem(n, 10))
