Kata

Description should be language-agnostic

• Node 18 should be enabled (Refer this and this for more info)

I don't like how example tests (for C# at least) do not contain cases for missing parameters. "If you are given too few arguments [...]" can be interpreted in a few ways, and it's somewhat puzzling when you get compilation errors on final tests.

Ruby translation. Please check and approve =)

Hi, I have a C# translation Kumited. However, I am a bit confused on how exactly you want the result to be rounded.

Do you want the result to be rounded (e.g. 0.02123 -> 0.02, 0.100321 -> 0.1) or truncated (e.g. 0.108231 -> 0.10)?

The description should explicitly state that the price should be rounded, rather than truncated.

If you are given too few arguments, or if they aren't numbers, then return 0.

In your random tests, the input you pass into the user function are all numerical strings and not actual numbers but they expect nonzero return values.

Are you kidding me? The day I publish my first kata, you "coincidentally" publish almost the exact same thing? [rolls eyes]

In your example tests you've got the actual and expected parameters reversed -- see https://www.codewars.com/docs/js-slash-coffeescript-test-reference -- which makes error messages look confusing, like this:

✘ Expected: '0.11173326617063674', instead got: '0.11'
