It's not so much a printing issue as an ease of manipulation issue. In base 16 I can go: In [30]: hex = "ee36"
In [31]: int(hex, 16) Out[31]: 60982 In [32]: int(hex[0], 16) Out[32]: 14 In [34]: int(hex[2], 16) Out[34]: 3 I would like to be able to do that with any base, so I could say: base1000 = base(1000, 34987563294875623489756324576) if int(base1000[0], 1000) > 900: Do_Stuff() ... I was doing a bunch of iterations using divmod to pull apart the integers, but then I realized that conceptually what I was doing was just change of base operations with really large bases, and so I think I can really clean up my code a *lot* if I can figure out a way to do this. As far as printing goes, it isn't that important to me, because once the base goes over 52 or so, things would start to get incomprehensible (i.e. e'k"rw12""34yf'4vw'e1234rkhfv'b124214"".124'5gew""rgsfv X 1000^-31) Thanks, --Connor On Tue, Jun 22, 2010 at 12:13 AM, Ondrej Certik <ond...@certik.cz> wrote: > On Mon, Jun 21, 2010 at 9:54 PM, John Connor > <john.theman.con...@gmail.com> wrote: >> Hello all, >> I was wondering how sympy handles numbers with different bases >> (positional notation)?
