OP solved it, closing

Agree

Maybe it should be specified that p/36000 is NOT the right way of going from an annual interest to a daily interest.
That indeed, it is a simplification to make the kata easier.

it didn't work for me either

great point

The final tests are comparing the actual/expected values approximately, so it may be possible to pass without ronding anything. This is true for Python (and maybe Ruby) as well.

This is a problem with float precision:

>>> 86.7 / 1.7 / 1.7
30.0
>>> 86.7 / (1.7 * 1.7)
30.000000000000004

happens with me too sometimes, i get white instead of red. Refreshing the page fixes it, but beware your code might get cleared:)

mmh?
