Calculators Algorithm for Calculator application

AI Thread Summary
To develop a GUI calculator application, utilizing existing libraries or language features like 'eval' can simplify the process of evaluating mathematical expressions. For those interested in understanding expression parsing, resources such as lex and yacc are recommended. Specifically for MATLAB, the focus should be on using its GUI library to construct strings representing mathematical operations, which can then be processed using MATLAB's eval function. This approach allows for the implementation of basic operations such as addition, subtraction, multiplication, and division without needing to create a complex algorithm from scratch.

I need an algorithm for developing a calculator application. When I googled , I got results that perform the ordinary push and pop operations . I need the complete algorithm that can be useful to code a calculator application in GUI.

What is the goal of your project?

You could just download a library that evaluates mathematical expressions (or use a language feature like 'eval') and then have your GUI build strings to feed it.

If you want to know how expressions are parsed you might want to look into lex and yacc

I am trying to develop a simple GUI calculator in matlab. I am going to perform simple operations like +-*/ . that's it.
 
I don't know MATLAB very well, but I'm guessing you don't need to worry about the algorithm, just use their GUI library to build strings and then feed those strings into matlab's eval function.
 

Thread 'The Human Cost of AI'

This week, I saw a documentary done by the French called Les sacrifiés de l'IA, which was presented by a Canadian show Enquête. If you understand French I recommend it. Very eye-opening. I found a similar documentary in English called The Human Cost of AI: Data workers in the Global South. There is also an interview with Milagros Miceli (appearing in both documentaries) on Youtube: I also found a powerpoint presentation by the economist Uma Rani (appearing in the French documentary), AI...

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
