Usage: dc [EXPRESSION]
This is a Tiny RPN calculator that understands the following operations: +, -, /, *, and, or, not, eor. If no arguments are given, dc will process input from stdin.
The behaviour of BusyBox/dc deviates (just a little ;-) from GNU/dc, but this will be remedied in the future.
Example:
$ dc 2 2 + 4 $ dc 8 8 \* 2 2 + / 16 $ dc 0 1 and 0 $ dc 0 1 or 1 $ echo 72 9 div 8 mul | dc 64 |
