Hello Mike, Hmm, I am afraid you are exaggerating a bit :-) 1) a positional notation making use of negative bases looks very awkward/impractical (you would have to utilize negative coefficients); OTOH, when working with such a positional notation, you are supposed to be working on N (ie the set of the "natural" numbers, or positive integers); and to add to all this, there are a number of approaches to the "construction" of N itself (Peano's, Cipolla's, the set theory with all its subtle problems... cf Bourbaki[sm]) 2) Pi, as "e" ~ 2.71828182..., is a **trascendental** irrational number (!). I let you guess what kind of coefficients you have to use to generate integers. Mathematics < manthano (~ I learn, aor. emathon) ;-))) Best regards, Salvo To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
