JavaScript Math Absolute

The Math.abs() method in JavaScript returns the absolute value of a number. This means that the method returns a positive number regardless of whether the input number is positive or negative.

Syntax

The syntax for using the Math.abs() method is:

Math.abs(x)

Here, x is the number whose absolute value you want to calculate.

Examples

Consider the following examples to understand how the Math.abs() method works:

Math.abs(-10)
// Output: 10

Math.abs(5)
// Output: 5

Math.abs(-3.14)
// Output: 3.14

Math.abs(0)
// Output: 0

In the first example, Math.abs() returns the absolute value of -10, which is 10. In the second example, Math.abs() returns the absolute value of 5, which is 5. In the third example, Math.abs() returns the absolute value of -3.14, which is 3.14. In the fourth example, Math.abs() returns the absolute value of 0, which is 0.

Conclusion

The Math.abs() method is a simple and useful method for calculating the absolute value of a number in JavaScript. It can be used in various applications like finding the distance between two points or calculating the magnitude of a vector.
