### toDecimalMark
Convert a float-point arithmetic to the [Decimal mark](https://en.wikipedia.org/wiki/Decimal_mark) form.
Use `toString()` to convert the float `num` to a string, then use regex to separate every three characters of the integer part with a comma.
Use [Ttemplate Literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) to return joined parts.
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) => {
let numberParts = num.toString().split('.')
return `${numberParts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ',')}.${numberParts[1]}`
}
// toDecimalMark(12305030388.9087) //-> '12,305,030,388.9087'
const toDecimalMark = (num) => num.toLocaleString()
// toDecimalMark(12305030388.9087) -> "12,305,030,388.9087"
```
