% echo 5k 1 3 /p|dc
.33333

isn't nearly as convenient as:
% fc 1 3 /
0.3333333333

especially since in rio i can just tack on " 60 +" to the end of that
line, click Send and thus manipulate the original expression with
minimal effort.

yes, i know they're more-or-less equivalent (but see below), but i
thought i'd mention it because since i wrote it i've found that it's
one of those tools that just "fits" really nicely.  no particular
feature in mind; i just find it consistently satisfying to use.  YMMV,
of course; i'll freely admit i'm biased :-)

i said *floating* point.

the set available by including libc.h, or some approximation thereof
(e.g. sin, log, sqrt, etc).

i presume hoc gives access to these also, but it's overkill for the
kind of thing i'm talking about, not to mention awkward to use on the
command line.
