Calc Angular

Calc Angular is an Angular calculator built as a clean-architecture port of the React version in calc-react. It keeps the same feature set while organizing the code around domain logic, application state, and presentation components.

Features

• Basic arithmetic with chained operations and repeated equals behavior
• Scientific helpers for square, cube, square root, cube root, factorial, reciprocal, percentage, and constants
• Memory controls for store, recall, and clear
• Language switching for English, Spanish, and Portuguese
• Accessible result output with responsive layout and visual regression coverage

Project Structure

• src/app/core/domain/ contains pure calculator logic, formatting helpers, and shared types
• src/app/core/i18n/ contains localized messages and translation helpers
• src/app/features/calculator/ contains the calculator facade and feature shell
• src/app/shared/components/ contains reusable presentation components
• tests/visual/ contains Playwright visual regression tests
