[Extremely Hard] Wired Calculator

[robertark]

Alright, I've never seen this done before -- and I can't figure it out myself, so why not make it a contest, right? The challenge is:

Wired Calculator.

Why not, right? I mean, it can't be that hard. Here's what it has to do (Along with having an output screen):

• add
• subtract
• multiply
• divide
• negative/positive (+/-)
• 1/x
• modulus
• square root
• x^y
• x^2
• x^3
• "(" and ")" grouping
• Sines
• Cosines
• Tangents
  
• Natural logarithm
• Calculations with Pi (add, divide, subtract, etc, etc)
• Memory Save
• Memory Call
• Memory Clear
• Memory Add
• Ability to convert to hex, octals and binary (BONUS!)

THIS CALCULATOR MUST WORK JUST LIKE THE WINDOWS CALCULATOR (click start, run, type "calc" without quotes)!

Replying Requirements: When you reply with your contest result, be sure to include the following:

• Pictures (at least 2 pictures)
• The SAVE file or ADV DUPE file
• Mods, addons, etc used

Here's what it should look like -- it's not a parser, just simply hitting buttons:



Extra notes: No premade expressions, adv dupes, etc. This is your own work, start it from scratch!

The calculator should work as these orders of operations (and similar):

1. I hit 3, +, 8 and =.
2. The screen shows 11.
3. If I hit * 10, then hit equals, it will show 110 -- therefore, I don't have to type (3+8)11 -- must work just like the real calculator
4. If I were to hit MS (memory save), then it should show me on a separate screen what the current memory is.
5. If I hit CE, the results screen will default to 0
6. Then if I hit MR, + 19, M+, MR, it should read 129.

Hope this helps, if not, check out Using a Scientific Calculator - Succeed in Physical Science: School for Champions or Scientific Calculator

UPDATE: The competition has been extended until November 21st, 2008! Reason: Didn't realize this was such a hard challenge (even though the topic shows Extremely Hard) -- Again, Good luck again to all entries!

A calculator that acts like an expression parser?
So you can input stuff like

( 5 + 5 ) * sqrt( 2 )
-> result

?

No, it'd be more of pressing a button. I posted an image above..

Doesn't IEF already have one of these?

Please re-read the challenge

Hmm can egate2 take a string (expression) and solve it? You could just have a console screen, an answer screen, keyboard, and the egate.

This is supposed to be a challenge. Make the calculator similar to the picture in the main post. No pre-made expression chips!

So you're saying that all the calculators in the world should be like the Windows calculator? Try a proper scientific calculator and you'll see just how shit the Windows one is.

Also, I'm working on CPU code for a Polish notation parser which is essentially a Lisp parser. And then you can be like "RARARARARARA."

Also, RPN is clearly the best way for a calculator to work. An RPN calculator is essentially an exercise in stack manipulation. I should make a CPU program for an RPN calculator using the wired keyboard.

[robertark]

Did I specify to work exactly like the windows calculator? Sure, but not EXACTLY, keyword: "LIKE" -- ie: You press buttons instead of typing shit in. And all RPN looks like is shorthand math.

This thread was obviously for a challenge, not for dicks like you to come flame others -- but guess that doesn't matter, either.
