The **toExponential()**** method** is used to convert a number into an exponential notation.

Here is the syntax of the `toExponential()`

method:

number.toExponential(x)

This method takes a number as a parameter to represent the number of digits after a decimal point. The number must be in the range of `0 to 20`

.

This method returns a `string`

value that represents the exponential notation of a given number.

Let's look at an example of this.

let num = 6.57769;//no.of digits after decimal is 1console.log(num.toExponential(1))//no.of digits after decimal is 3console.log(num.toExponential(3))//no.of digits after decimal is 8console.log(num.toExponential(8))

- Line 1: We declare and initialize the number
`num`

. - Line 4: We convert the given number
`num`

to an exponential form, which has`1`

digit after the decimal point. - Line 7: We convert the given number
`num`

to an exponential form, which has`3`

digits after the decimal point. - Line 10: We convert the given number
`num`

to an exponential form, which has`8`

digits after the decimal point.
