### toDecimalMark
|
|
|
|
Use `toLocaleString()` to convert a float-point arithmetic to the [Decimal mark](https://en.wikipedia.org/wiki/Decimal_mark) form. It makes a comma separated string from a number.
|
|
|
|
```js
|
|
const toDecimalMark = num => num.toLocaleString("en-US");
|
|
```
|
|
|
|
```js
|
|
toDecimalMark(12305030388.9087) // "12,305,030,388.9087"
|
|
```
