bc in urxvt script and what are you using?

bcterm

starts or activates bc wcalc calculator in urxvt window in the middle of the screen.

https://raw.githubusercontent.com/bront … bin/bcterm

Can be linked to some button in wbar or openbox menu or from cli ...

p.s. This was decided to happen after testing about half dozen various GUI calculators out there.

changelog:
- wcalc (history, easier floating-point behavior) replaces bc

to test:
- apcalc (calc -d)

Like it. Nice one.

I prefer qalc to bc. The one I use actually. Will borrow your script with a twist.

funny how you always end up with 42...

anyhow, i'm using xcalc.

Actually much more interesting than this script is the info on what you people are using. Keep them coming. A "why" would be great addition as well. p.s. about 42; big fan of Douglas Adams.

Interesting idea. What options/alternatives are available with decimal justification, which was the standard for printing calculators?

Lots of options to explore here (answer 231)

I prefer to use the Korn shell's built-in let command and double-bracketed arimethic expansion, as per http://www.ibm.com/support/knowledgecen … h_eval.htm, mainly because I always have a shell open anyway.

For more complex operations, I prefer xcalc(1) -- death to toolkits! ]:D

HOAS, like:

echo $((3/2)) # ?

Head_on_a_Stick · 2016-11-13 16:19:26

^ Yes, exactly so.

Although I prefer:

print $((3/2))

The print built-in for ksh is much nicer than echo...

Actually, this is a bad axample because ksh(1) doesn't do floating-point -- I have to use zsh for that:

I like wcalc more and more, the problem is it will always print "Enter an expression to evaluate, q to quit, or ? for help" when starting interactive session.
