JavaScript Math Reference

This guide is your complete reference to every Math property and method in JavaScript, all in one place — clean, concise, and ready to bookmark.

What is the Math Object?

The Math object in JavaScript lets you perform mathematical operations on numbers — everything from trigonometry and logarithms to rounding and random generation.

Math.sqrt(16); // 4
Math.PI;       // 3.141592653589793
Math.random(); // 0.5739201837

Commonly Used Examples

Math.max(10, 20, 5);  // → 20
Math.min(2, -3, 7);   // → -3
Math.pow(2, 3);       // → 8
Math.sign(-12);       // → -1
Math.floor(4.9);      // → 4
Math.random();        // → random value between 0–1

Want a random integer between 1 and 6 (like a dice roll)? Here’s your quick snippet:

Math.floor(Math.random() * 6) + 1;
