Yeah, I agree with this.

To be honest, I personally have no thoughts to make the shell
to handle float point, and by now I don't see any person request
that, for most situations we just use an round up number
to satisfy ourselves.

But anyway, I have no objection to improving that. Feel
free to submit a patch :).
