I was just thinking that we don't yet define a Rationals or Floats Set but they could be
Rationals = imageset((x, y), x/y, S.Integers*S.Naturals) Floats = imageset((x, y), x/2**y, S.Integers, S.Integers) Containment order would be Reals contain Rationals contain Floats contain Integers contain Naturals0 contain Naturals Would there be any advantages to having these defined? /c -- You received this message because you are subscribed to the Google Groups "sympy" group.
