I was solved by checking nFloors by zero.

My error was the same and was solved by eliminating the use of the method substring

I am having the same issue. Did you manage to find the solution for this by any chance?

Not an issue.

in C# "expected 51.199999999999996, but got 512" I get good results in console. Any tips?

9510.662430555567, but got 951066.2430555555
57.03333333333333, but got 570.3333333333334
2190.3425000000007, but got 219034.25
66.02499999999999, but got 660.25
57.42833333333374, but got 5742.833333333333

Seems kinda random - good results in console everytime

Java random test throws java.lang.reflect.InvocationTargetException
basic test works, and everything works in compiler

It would be really nice way to ban cheaters. Put something useless in your code and everyone who just copies it should be banned.

Add bigger sample tests
