Have you written a calculator?

Post Reply New Topic

I wrote one in VisualBasic for computer class. It was just basic math, though.

I did a command-line calculator in Fortran. And also in Python, but that doesn't really count because it's just a call to "eval".

Yeah, I wrote a caculator - it fillled a void in my life just before I left school. It was a javascrpt versio of the windows scientific calclator and it eventuall ran to over 5000 lines. Yo coul change the background colours, nmbr base etc. It was a bit excessive but it was before I had any real world programming projects to do

I love Python for that - it makes things so easy to do. You want something done - you just code it. It's easy enough to get things done with.

I just use IDLE for python as a calculator. You can type in anything at the command line and it'll spit back the answer (or an error). I find it much easier to be able to type 3*4 / (5.**3) and get 0.096000000000000002 back (which I can point a variable to to simplify further steps) rather than have to fiddle around with a calculator GUI. It does have it's quirks though, like the decimal point in the "(5.**" which is there to tell it to use floating point rather than integers (otherwise it returns '0' as the answer), but the quirks are really just an expression of how flexible it is.
