RangeError when trying to access dashboard

[ryanlecompte]

Hello,

I'm getting the following error when I try to access the dashboard at /split:

RangeError at /split
can't convert -8.659560562354933e-17+1.414213562373095i into Float
file: dashboard.rb location: to_f line: 32

Does this mean I've somehow setup the experiment wrong?

Thanks,
Ryan

Potentially, which version of split are you using? And can you paste in the your ab_test method?

[ryanlecompte]

Split 0.3.0 and the error has suddenly gone away now. Can't reproduce! I will keep trying though. It may have been Redis funkiness, not sure.

Thanks!

Weird, that number ( -8.659560562354933e-17+1.414213562373095i ) is already a float as well, just a very tiny one.

It looks like that to_f call on line 32 isn't really needed so if you get that error again I'll look at removing it to see if it fixes it.

I just got this same error on version 3.3. It was occurring in testing when I had negative values for non-finished participants (e.g. more completed than participating)

I've just pushed a fix for this, could you try it out and see if you still get the same problem?
