"An Interval reversed is generally an Interval, except when made of Float."
Should ReversedInterval be renamed to ReversedFloatInterval then?+1Interval was designed for Integers only. IMO, it should be copied to a separate class, FloatInterval, to implement this capability.
Nonetheless, this seems to fix #testIntervalOfFloatLast and
#testIntervalOfFloatReversed of IntervalTest. Do we want to integrate
this proposal or shall we mark these two tests as expected failures?
