 Command-line calculations using bc

If like me, you do most of your work from the command-line, using vim to edit files, mutt for e-mails, cd/ls/mv/find/etc instead of a file manager, then you may get annoyed by having to fire up a GUI calculator to make (what may sometimes be) a single calculation.

This article shows how to quickly perform standard calculations on the command line including addition, subtraction, multiplication, division, square root, powers, conversion from decimal to hex, decimal to binary, hex to decimal, and binary to decimal. It also briefly introduces using bc in interactive mode and how to write files for use with bc for frequently repeated operations. There is a mention of using Google for performing calulations. It finishes with a little challenge to test the power of your CPU.
