A simple arithmetic calculator is a program that performs basic arithmetic operations such as addition, subtraction, multiplication, and division on numbers provided by the user.
Addition: Adds two or more numbers together. Subtraction: Subtracts one number from another. Multiplication: Multiplies two or more numbers. Division: Divides one number by another (ensuring the divisor is not zero).
To use the calculator library in your Node.js project, install it via npm:
Run npm i twilight-calc
`` // Import the calculator module const { add, subtract, multiply, divide } = require('twilight-software-package-calc');
// Use the calculator functions console.log(add(5, 3)); // Output: 8 console.log(subtract(10, 4)); // Output: 6 console.log(multiply(2, 6)); // Output: 12 console.log(divide(8, 2)); // Output: 4 ``
add(a, b): Adds two numbers a and b. subtract(a, b): Subtracts b from a. multiply(a, b): Multiplies a by b. divide(a, b): Divides a by b.
Adjust the import statement (require('twilight-software-packagecalc')) and function calls (add, subtract, etc.) based on your library's actual structure.
Provide additional documentation, examples, and usage scenarios to help users understand how to integrate and use your calculator library effectively. Including code snippets, explanations, and sample inputs/outputs can be very helpful.
Consider adding tests for your library using testing frameworks like Jest, Mocha, or Jasmine. Provide instructions on how users can run these tests to ensure the correctness of your library.
