A handy calculator

bc
bc is a wonderful calculator. Just type bc at the command line and have at it. Ctrl+D (or type quit) will get you out. This usage is just scratching the surface: bc can handle a mini scripting language, complete with variable, statements, loop, conditional statements and more. Do a man page on it to find out.
Sample Output
$ bc -q
23.79 * .15
3.56
(press Ctrl+D to exit)

What Others Think

bc is handy. Great for number base conversions (hex/dec/octal/binary). Tnx for pointing out the scripting!

you might start bc with -l option which enables standard math library. Without math library, even a simple division is rounded. bc 45/8 5 When it's enabled: bc -l 45/8 5.62500000000000000000
