it's ok if you stick to 32 bit and don't do divisions.

personally for off-the-cuff command-line calculations
i've been using my own "fc" for years and
years. nothing else quite hits the spot, but
i'm biased.

my reasons: hoc doesn't do bit level ops, has too much syntax that needs
quoting, and if you're quoting, it's awkward (in rc) to insert
environment variables inside the quotes. dc
doesn't take command line arguments,
doesn't do floating point and its output isn't suitable
for as input.

there's a man page for the inferno version of fc here,
in case anyone's interested:
