Can anyone explain to me how do you calculate m?

I am trying to understand this kata and I am having difficulties with it

The task should be clearer...

solved it, thanks though.

Hello Community,

When I do the tests I pass them all. When I submit the code I pass most of them except 3. I thought the problem was that the value of n were floats and I adjust the code accordingly. However I keep getting the same errors. When I run the code in my computer with those values, assuming the values are referring to n, my code works just fine.

Any hints?

3263.10819218804 should equal -1
1.464758190332126 should equal -1
9400.896936434361 should equal -1
