In this article, I will show you how to perform numerical conversions in JavaScript efficiently. JavaScript is a programming language that is widely used in both web development and mobile application development. Knowing how to properly perform numerical conversions is essential for working with numerical data in JavaScript.
Numerical conversions in JavaScript
JavaScript offers several built-in functions that allow you to convert between different number bases. Next, we will see how to convert to and from decimal, binary and hexadecimal bases.
Conversions from decimal bases
To convert a decimal number to binary in JavaScript, you can use the method toString() and specify the base as 2. For example:
let decimalNumber = 10; let binaryNumber = decimalNumber.toString(2); console.log(binaryNumber); // Output: 1010
Similarly, to convert a decimal number to hexadecimal, you can use the method toString() and specify the base as 16. For example:
let decimalNumber = 15; let hexadecimalNumber = decimalNumber.toString(16); console.log(hexadecimalNumber); // Output: f
Conversions to decimal bases
To convert a binary number to decimal in JavaScript, you can use the method parseInt() and specify the base as 2. For example:
let binaryNumber = "1010"; let decimalNumber = parseInt(binaryNumber, 2); console.log(decimalNumber); // Output: 10
To convert a hexadecimal number to decimal, you can use the method parseInt() and specify the base as 16. For example:
let hexadecimalNumber = "f"; let decimalNumber = parseInt(hexadecimalNumber, 16); console.log(decimalNumber); // Output: 15
Using numeric conversions in JavaScript
Numeric conversions can be very useful in a variety of scenarios in JavaScript. Some common examples include:
- Perform arithmetic operations with numbers in different bases.
- Manipulate information encoded in binary or hexadecimal.
- Convert numbers in binary or hexadecimal format to a more readable format for display purposes.
By mastering numerical conversions in JavaScript, you will be able to work more efficiently and effectively with numerical information in your projects.
