Hi, sometime i feel like the calculator included with windows cumbersome, because it dont allow u to see/write more 0 before the number, has no separator or quick way to see a large number easily ect, little anoyance like that, so i was wondering if someonw knew of a good calculator for programming they found or even made themself, that would be great. I searched a bit a can't find one i like or that is free. Thx for ur help in advance.

Eh?

I'll use the google calculator for certain things the windows one doesn't do, but I don't understand your gripes to even consider if that'd be helpful to you...

I use my TI-83. I needed it for class, and it comes endlessly handy. It's also nice to have something not attached to the computer once and a while.

I use my debugger's watch window. Expecially since most the calculations I need to do are from numbers in game anyway, just drag a few variables together put a * or + or whatever sign in there, and check what my new value is. And it handles hex, so all the better for address calculations and such when digging through assembly for information on a crash.

[View -> Digit grouping] will fix your "no separator" problem.

Can't beat Calculator for quick decimal<->hex<->binary conversions. For anything more than just a quick addition or multiplication, I bring up Matlab.

A scripting language with REPL is good for many tasks.

I use the Windows calculator. The only time I ever need to use it is when I need to convert a decimal number to hex or hex to decimal.

If I actually need a calculator I just write a little bit of code and run the program.

I suppose that an actual calculator would be nifty for double checking to see if you're doing things right in your program though...

the calc that comes with ubuntu suits me. its got leading zeros and digit grouping, and it can do much more that windows calc, such as square root without having to use the x^y button.

You don't need the x^y button to do square roots with Windows calc. You can also use Inv x^2

I use the Windows calculator and KCalc on Linux.
For more advanced math, I use wxMaxima and a good sheet of paper.

Python.

Really, run in interactive mode it makes one of the best and most flexible calculators out there.

Google will do as well: '0x10 in decimal' or '16 in hex'. Octal and binary work too. :)

You would be surprised. Quite often you always have a browser open, set to the Google search page.

The other reason I like Google is because I can convert between different units of measurement. It is very handy.

If there's something that the windows calculator won't do for me (rare occasions) then I use my Casio Graphics calculator, fx-9750G PLUS is the model name/number. Although it's not cheap, around 90USD, but damn useful for almost anything you want to do with math.
