Looks like dc’s base conversion is buggy:

The following command (copied directly from the table above) reports that 360 in octal is equivalent to 132 in hex.

dc -e”8i 16o 360 p”

In fact, 360 in octal is equivalent to F0 in hex.

I was looking for a binary to decimal converter and backwards to use in a shell script. I checked the dc man page but didn't find any options... I was thinking of writing a shell script with expr to do all the computations but then I found your page :D This was really a life saver, couse I'm not that good at math :) Thank you very much!
