Unix Math Calculations

I just ran across http://x-bc.sourceforge.net/index.html. If you've ever used the Unix bc calculator utility, this project provides two excellent extensions to the built in capabilities of the calculator. In particular:

http://x-bc.sourceforge.net/extensions_bc.html

http://x-bc.sourceforge.net/scientific_constants_bc.html

You'll get a wealth of math functions available to you by simply including the extension files avaiable at those URLs.

In order to have these extensions always loaded as well turn on the built in math extensions, you can alias your bc command as follows:

alias bc="bc -l ~/bin/*.bc"
