There are many JavaScript Number methods that are often used to manipulate number values. These number formats support integers, floating-point numbers, such as decimal, hexadecimal, notations.

Here are a few methods that can make manipulating and modifying numeric values much easier.

## JavaScript Number Format

### `1\. Number()`

The `**Number()**` method converts a string into a number.

``````// Example 1
let x = '10'
let num = Number(x)

console.log(num)                 // Output: 10
console.log(num * 9)             // Output: 90
// Example 2
let x = true
let num = Number(x)
console.log(num)                 // Output: 1
console.log(num + 9)             // Output: 10
//Example 3
let x = false
let num = Number(x)
console.log(num)                 // Output: 0
console.log(num + 9)             // Output: 9``````

In the example above, `Number(value)` method is used to convert string `x` to an integer and perform operations on the number value. Setting `x` to`true` returns 1 and `false` returns 0.
