The Power of Logic: Calculator

Archive: 2 posts


As a challenge, i wanted to create the most advanced calculator possible within the confines of the LBP2 Betas thermometer. I am hoping that it will showcase the true power of LBP2's logic, although as the level goes it is pretty useless but there are many uses that the system could be adapted to suit; I'm taking things like complex AI and Saved game code generators and probably many more but we'll have to see, i do hope that i can at some point clear up the units enough to allow easier access for other users.

Features:
- Eight digit values
- Addition
- Subtraction
- Combination's of negative and positive values (e.g 78751278 + (-76598726))
- Fixed decimal points (the point is fixed at same between values e.g 1234.3321 + 1234.3321 = 2468.6642)

Planned features:
- Multiplication
- Division
- Adaptive decimal points (Allowing for decimal points in various places)
- Fractions

It would be nice to attempt algebraic functions if (And i mean if) i get the above complete but that could be after LBP2 is released.

As of now i can see no problems with the values i have tested but the number of combination's possible means there may still be errors.

The Tech: I hope to put this into a tutorial level at some point as to allow other people to use it.

The Calculators main component is a BCD adder (Easier to decode into decimal) for those who know a little about logic it's different from full adder in that after the value 1001 (9) it has to reset it's value to 0000 and begin it's counting process again. The addition side uses a pure set of BCD adders wheres the Subtraction uses a 9's compliment set. I'll tally up the logic I've used soon.

Current thermometer usage is amazing at around the third notch if i remove the controlanator and the input displays it approaches around half a notch, I am more than surprised.

UPDATE: Decided not to do anything with this project until the release of LBP2.

I hope to demonstrate the true power of LBP2 logic.there many applications that the system could be adapted.It provide a Some Feature Like Combination Of + and - Values,Addition,Sus traction and So On.2010-12-02 17:39:00
