Hi,
Here is a new tool, to play with. It's just a one-day project, so it might have some bugs.
It's a calculator, that you can give any "valid" equation, and it tries to calculate a float result. The supported functions are:
-,+,/,*,^,sqrt abs,round,floor,ceil sin,cos,tan acos,asin,atan cosh,sinh,tanh
it also knows PI as a constant and it supports brackets as well. Synthmaker doesn't support recursive algorithms, so I had to use a different approach -> loops 😈
Have fun!

wow thats badass! I wonder if we can further evolve this were we can have variables like x

Excellent work, Myco. 🙂 I haven't been able to catch it out yet - even the precedence of *,/ over +,- seems to work perfectly!

Aha - one day!
Anyone else feeling like an complete idiot? 😉

Excellent Lavorone 😉 1+1-6+(-1*2) but this does not seem to work well

Yes 😊
MyCo, so nice you being active again! BTW, is "floor/ceil" = min/max?

I do not know if this is the best method, but I added a module to check if the equation has been solved or there are new elements to be calculated. so it seems to work fine.

floor = round down ceil = round up

The fix does work, but i'm not sure if this is a good solution, because inside a loop you restart it. I guess the problem is the sign again. I tried to fix that before. But this case is not handled.
The calculator does 1+1-6+(-1*2) this way: brackets first: -1*2 = -2 result: 1+1-6+-2 now it does the minus (from right): it has no left param so it does 0-2 = -2 result: 1+1-6+-2 now it does the same minus again, because it's the same equation, but it should do 1-6 now come plus (from right): -6+-2 = -8 result: 1+1-8 plus again (from right): 1+1 = 2 result: 2-8

I noticed that the result would stop at 2-8, so I decided to do a check on the string and see if it was empty, it starts only if the string is not empty and still contains an operation there.
I also believe it is not the best solution. 😕

Ok, I deleted the module created in the previous version, and I believe I have located the problem, the first loop calculation was not initialized correctly. I hope this works well now.

What did you change ?
DigitalWhiteByte ·
In the screen that appears when you loads the schematic I made the changes by adding links and reordering trig.
Trig order: 1. get the string equation 2. to loop through occurrences. (link added) 3. to loop through ops
I removed the S & H before the module "doubled signs", it seemed superfluous at this point.

OK, here is my fix for the above problem, and also for another which happened with stuff like:
1-1*-1
The basic of the fix is, that the calculater now differentiates between a sign flag and a minus operation. A flag has high priority, and the operation has low priority.
