With the current standards and being a 8kyu, assertion messages (inputs) must be provided to fixed and random tests at least to aid beginners in debugging

Thank you. Republished

With the issues addressed and closed, you can republish the kata.

Changed to margin of error.

Changed to margin of error on perceived time per JohanWiltink's comment

Rounding is not the correct way to handle floating point representation inaccuracy, testing with an error margin is. This is documented.

Round to 2 decimals.

This is not enough information. In addition to the required precision, the kata should also specify the rounding method (e.g., half-to-even), and when to apply the rounding (e.g., on the sum at the end).

Thanks! It works well now

No sample tests.
