Added random tests to Ruby. Crystal, JS, PHP, Python already has them.

Coffee, C#, Haskell still needs them.

Fixed. Added randomized tests.

Rounding at 10th decimal place will not always give you 10**-10 accuracy.

e.g What if the number is around 0.0001? :)

You're not meant to round them to 10 places when precision is None. You're meant to output the exact value.

Now I'll leave it to you to figure out how many places is enough ;-)

"Four consecutive 1's must occur in a sequence." Looks good. Thanks =)

I've already changed it to 1,1,1,1. If you have any ideas how to express it more clearly don't be shy.
