Okaaaaaaaaaaaaaaaaay
Anyway moving on
Is it going to ask a question like my (simple) calculator
Or is it actually going to have graphics ?

Hadlab · 2011-04-04 12:11:01

I have a very basic calculator to help: http://scratch.mit.edu/projects/Hadlab/1686488

midnightleopard · 2011-04-04 16:34:22

I would do it but you have tons of collab team members already.

Since no one wants to do the postfix stuff, how about this:

Code:

Break input into list "input"
Until all parentheses are dealt with:
   Scan from beginning of "input" for "("
   Scan from beginning of "input" for ")"
   Add locations of these two parentheses in input list to list "parentheses_locations"
Until finished all locations in "parentheses_locations," start and end (innermost parentheses)
   Evaluate items in "input" list between"parentheses_locations"
   Replace items in "input" list with new value.
Display value

Hmmmmm...
Scratch doesn't have any blocks for scanning inputs. But, we could store the inputs in a list...

When I receive 'input'
Set counter to [1]
repeat 'length of [input]'
add letter [counter] of [input] to inputlist
change counter by 1

Sorry if that wasn't clear. That step was supposed to be represented by "break input into list "input."" This is a very rough draft. The actual program would require several temporary variables for scanning first the input, then the lists. I think we should strive to make this 0s1s, so in fact, no broadcasts required.

It's funny, I'm doing the same thing, just by myself. Sigma Alpha

rubiks_cube_guy238 · 2011-04-04 20:24:36

I made a graphing calculator-type thing myself which, while slow, can compute almost any equation with input x.
Here it is.

Ohkay... 0s1s. Not too hard and much cleaner and faster. big_smile

what if we want a loading icon?

Hardmath123 · 2011-04-05 01:35:43

Tell me if you can see the above image.

I like the list idea, but this means we have to start over. I guess it's ok, we haven't done much anyway tongue

jji7skyline · 2011-04-05 01:56:53

Are you sure you don't need any button sprites?

Hardmath123 · 2011-04-05 04:10:16

Well, we already have applejack for all graphics hmm , you can ask him if he needs help.

Really? The block lib banner's longer hmm

P.S. I think you should stop working on the bracket opener. We've started to lean towards an engine which converts the whole thing into a list first, which means any non-list-based engine will be obsolete sad

OK. It's the text that's too long for a sig.

I thought BBCode got eliminated?

No.

ONTOPIC: So I should cancel what I'm doing now? sad

Hardmath123 · 2011-04-05 06:40:42

Yeah sad I'll have to delete the setup engine and my work on the non-bracket solver. This better make life easier tongue

*gasp* you're right!

scimonster · 2011-04-05 06:43:03

You know what we forgot in the setup engine? × and ÷ yikes

Who uses those? The standard ones are actually * and /.

How are we gonna do factorials. I made a factorial block (in the block library), but that won't work here.

But they get used anyways. hmm
I do not know. I suppose with a repeat method...

Code:

set [count] to [0]
set [factorial] to [0]
repeat (number)
  change [count] by (1)
  set [factorial] to ((factorial) * (count))
