Show 2 digits before decimal and show 3 digits after decimal point

The number is a single digit or whatever its, I want the value as before 2 digit and after 3 digits in decimal value.

Received values:
7, 
07, 
07.1, 
07.10, 
17.222,

Expected output:

07.000,
07.000,
07.100,
07.100,
17.222

>Solution :

function formatNumber(number) {
  return number.toFixed(3).padStart(6, '0');
}

Does this do the trick for you ?
