JavaScript Math
JavaScript Math
JavaScript provides a built-in Math object that allows you to perform mathematical operations, such as rounding numbers, generating random numbers, trigonometry functions, powers, square roots, and more.
The
Mathobject works without creating an instance, meaning you use it directly:
Common Math Properties
| Property | Description | Example |
|---|---|---|
Math.PI |
Value of π (Pi) | console.log(Math.PI); // 3.141592653589793 |
Math.E |
Euler’s number | console.log(Math.E); |
Math.SQRT2 |
Square root of 2 | console.log(Math.SQRT2); |
Math Methods
1. Rounding Numbers
2. Power and Square Root
3. Absolute Value
4. Min and Max
5. Random Numbers
6. Trigonometry
Examples
