Hexadecimal! That's pretty neat. I'll put that in my man page.
The syntax required by dc is pretty different, so I worked out some
examples and put those in my man page:
dc 4 8 + 4 4 + + p
20
dc 4 8 4 4 + + + p
20
dc 4 8 + 2 / p
6
dc 2 2 + 2 2 + 2 2 + + + p
12
dc 2 2 2 2 + + + p
8
dc 2 2 2 + + p
6
dc 2 2 2 + + 3 / p
2
dc 8 8 \* 2 2 + / p
16
If it wasn't for the examples given by 'dc -help' I'd have been
totally stray.
No sign of base 2 yet (?).
