    33* q(x)=1-x^d^ with d the contfrac period for quad. irrationals (=infinite sequence)
    44* other p/q, e.g. (2+x+2x^2^-3x^3^-x^4^+x^6^)/(1-2x^3^+x^6^) for e. Of course, absent a theory these must be guessed but that code exists already.
     5* would make e+sqrt(2) exact
    56
    67Arithmetic with p/q is obvious, only back-conversion to non-rational looks impossible at the moment to me.
