This project was bootstrapped with Create React App.
Simple calculator built with React and some hooks with basic functions, operations and an intuitive design.
- Looks like a real world calculator.
- Uses the UseContext hook so the screen and buttons components are connected.
- Uses the UseReducer hook so the state can be handled easier.
- Can handle 12 digits max to avoid overflow.
- Basic operations (+,-,*,/) but with the capacity to add more operations in the future.
- Support for decimals and negative numbers.
- Round up numbers to 2 decimals so it doesn't overflow.
- Buttons to delete and clear the screen.
- Can chain operators so you can avoid having to push the equals button until the very end.
- Shows error messages.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
