It can calculate values, solve equations, and do simple graphing.Yeah my go to calculator these days is just the Haskell interpreter GHCi - arbitrary precision integers, can write full expressions and have history so I can go back and make changes, saving values in variables, a broad range or types IEEE-754 Doubles, Rationals, and the numbers package gives you things like the arbitrary precision CReal type: > cabal repl -build-depends numbers In all seriousness, though, Wolfram Alpha is pretty cool if you need to look something up quickly. 512 MB or more (recommended)ĭude! I don’t have 64 mega- Gauss of video memory… That’s like right in the middle of an MRI scan and a neutron star, on a log scale! Windows XP (32-bit) with Service Pack 3 (SP3)ġ GHz Pentium processor or equivalent (recommended). Apparently it became it’s own project which turned into Microsoft Math 4.0, but no one told me. Well, it turns out they did not ditch it. There’s a similar widget in OSX that actually using Safari’s Javascript engine. This is how a real software calculator should look like: ![]() I think the reasoning is that the calculator has some functions where it’s not obvious which keys you would use (memory functions, sqrt, 1/x and also much more in scientific mode.) And then it would be silly to include buttons for just those functions and not the numerals and other operators. Why do you need virtual buttons on the screen? Not exactly a TI-8* replacement, but it does have parentheses and essential scientific functions and compares with an ’80s/’90s non-graphing scientific calculator. :)įor the record, this is not a calculator: As you might’ve noticed, MatLab is very much focused around the use of matrices. “Mat” doesn’t stand for math, but matrix. But I guess the fear was that clueless users will be frightened by a UI that does not look exactly like the Mickey Mouse calculator. Breaking with them would yield a better, more user friendly application. Why can’t they use a scrollable window with calculation history? Why use the silly MR, MC functions when the user can copy and paste results? Some of these design choices are just blind replication of functionality. Still, some “features” do not make sense. At least that’s my opinion.Īnd yes, it was designed for average non-scientist, non-techie user. Why? Am I missing some fine point of screen shot taking on Eric:įirstly, hating math is like hating gravity or oxygen. I took the rest of the screen shots myself using Alt+PrintScr. I only stole the TI pick, the Mickey Mouse and the iPhone app (out of laziness really). Well, other than my occasional dabbling with Nathan:Īlso, very true – why the hell are the TI calculators still so expensive? It’s MrJones: I mean, I see it’s benefits – I just never actually used it. Everyone actually wanted to borrow it for the tests because it had the automatic solvers and Chris: The upside was that mine had more features. The downside was that we could not share games. I decided to buy the slightly newer version because I had no clue which one I needed. Is it worth buying the iPhone app for jambarama: Btw, I found some TI calc emulators of the iPhone but none of them are IceBrain: I remember these things to be freakishly Rob: It was sort of a running joke – each semester he would find some excuse to lend it to an unsuspecting, clueless student and watch him squirm. One of my CS professors had one of those. This is how a real software calculator should look Athanor: Its silly, counter-productive and it happens all the time. This is a classic software engineering trap: replicating functionality instead of improving and automating it. But if you are making a software calculator there is just no reason to make it work this way. Secondly, the cheep calculators (like my Mickey Mouse specimen) could not display and maintain history of calculations because of hardware limitations. Chances are your keyboard has a numeric pad section shaped exactly like a calculator keyboard (unless you are on a smaller laptop or notebook). First off, you are sitting at a computer which has a keyboard with lots of buttons. ![]() And Google image search delivered!Īnyways, making a calculator program that looks and behaves exactly like a cheep $3 calculator is kinda silly for multiple reasons. I’m fairly sure it got smashed to pieces or lost, at some point doing my childhood but when I wanted to find a picture of a generic, simplistic calculator this is what popped into my mind. I have no clue why I remember this particular calculator rather than all the other ones, but I do. Btw, I actually owned a calculator just like this when I was a kid. Raise your hand if you also owned this calculator as a kidĪnd they are about as useful.
