Scientific Calculators

Post by Ambush Commander »

I simply must have calculators that allow you to enter a string of operations, press equal, and see the final answer. Like CASIO's fx-115MS. So when I'm on the comp, and I need to make a calculation, I actually end up busting out my CASIO to do the calculation.

I simply cannot use the single screen calculators!

For really complicated things, I load Mathematica, but it's a bit too powerful for most tasks.

Ah, it would be so great if I had a simple computer calculator that worked like this:

Code: Select all

(234*435)/(23*493)+32
Nothing fancy. But quick computational power when you need it. I also think it's a pain typing numbers on a console. Maybe that's just me (have to practice typing on my number pad).

When you need to calculate something, how do you do it?

Heh ... I've used PHP CLI in a hitch. ;) But I try to keep my TI-83 handy for such things.

But there's gotta be some simple string-based calc software out there. Now I'm curious... off to SourceForge!

windows calculator, or if it comes to it i write a PHP script to do it for me

Code: Select all

<?

var_dump((234*435)/(23*493)+32);

?>
and run it off my server (I hardly ever use the CLI for PHP, it's a hassle to ssh in the box when I almost always have my FTP open)

Ah, but PHP won't give an exact fractional answer. It'll give some machine (im)precise float. And we all know about the evilness of floats.

SourceForge... hmm... good idea. If there is nothing, I've finally found a use for my Polynomial/Fraction classes!

Qualculate might do the trick, if you're on Linux. Got a lot of dependancies, though. And you're SOL if you're on Win32.

There are some other calculators, but all the ones I found were for Linux. The only Win32 one I found was GraphCalc but it seems a bit much...

SOL for Qualculate. GraphCalc does seem a bit heavyweight... Mathematica for my complex graphing needs.

Now, if you wanted to get the answer in fractions...

Would indeed be a good reason to try out a GUI setup for PHP. And you could use your fractional/polynomial classes! ;)
