Conditional indexing issue with float precision

Hi,

I figured out another workaround: just defining comparison operators taking into account approximate equality:

 (≲)(x,y) = <(x,y) | ≈(x,y)
 (⋦)(x,y) = <(x,y) & !≈(x,y)
 (≳)(x,y) = >(x,y) | ≈(x,y)
 (⋧)(x,y) = >(x,y) & !≈(x,y)

So, replacing >= by ≳ and < by ⋦ seems to make the range examples work with floats work as expected for rationals/integers.
