Minecraft Scientific/Graphing calculator - Sin Cos Tan Log Square root

Hello there!
(Reddit name: MaxSGB)
Here is the project I've been working on ^.^
Specs: 6 digit addition and subtraction, 3 digit multiplication, division and trigonometric/scientific functions. (The reason these are only 3 digits is because multiplication and division would take a long time to decode/complete/encode. Also, the fraction display is hard enough to build for 3 digits, let alone 6 - 6 digit RAM would not only be massive, but a bit pointless since the curves follow the same pattern surrounding the peaks.). Graphing y=mx+c functions, quadratic functions, and equation solving of the form mx+c=0.

The screen and keypad were always meant to be the main feature of this machine. The main display boasts 25 digits. Square root signs are displayed and can change to accommodate any number of digits. Square root signs, add, minus, multiply and divide signs are displayed at appropriate times, and there is a full fraction display. The 7-segments for the fractions are the smallest possible, being only 3 wide, and stackable vertically and horizontally.

I made a custom texture pack for the keypad, and made wooden pressure plates invisible in order to get the best effect.

The calculator itself is just over 250x200x100 blocks. It contains 2 6-digit BCD number selectors, 2 BCD-to-binary decoders, 3 binary-to-BCD decoders, 6 BCD adders and subtractors, a 20 bit (output) multiplier, 10 bit divider, a memory bank and additional circuitry for the graphing function.

Thank you very much for watching. As you can probably imagine, this took some effort to make, and so a like would be very much appreciated. =]

Serious question. What does the system do if you divide by zero?

[SgtGodswordBerserker]

It beeps, like at 10:45 - the same beep that it will make for any invalid calculation. i.e. one that cannot mathematically be done or that results in infinity.

This is scary.....

I guess this guy knows how to make a real calculator.

O_O I'm stupid or you're a genius...

How do you manage to keep all those chunks loaded...?

[NekoV Nyuu]

Respect ! This is amazing !

[SgtGodswordBerserker]

Although, as Joshua Osborne pointed out, it did kind of tell you the answer in the video...

[SgtGodswordBerserker]

Have now... Sorry it was so late... Exams...

And imagine the feeling of it broken in 1.5...
