Float array elements are sometimes converted to integers

[MartinNowak]

[30.0, 27.2, -2.0].mongoize returns [30, 27.2, -2.0] and [30.0, 27.2, -2.0].mongoize.map{|e| e.class} returns [Fixnum, Float, Fixnum]

I found this while storing geo coordinates using a Mongoid model. Some of the coordinates are now Integers while others are Floats.

Apparently it's done deliberately (see here and here), but it makes no sense to convert floats to integers, just because the fractional part is zero.

I think this was added to fix another issue, see https://github.com/mongoid/origin/commit/701a8f777c6e9c6d8ca14657e07a6128407ef828

So when you have "2." it would convert to 2... but 2.0 should be a Float IMO.

@MartinNowak want try to fix this and send a PR? thanks

[MartinNowak]

Sure will do.
