Use the toFixed() method to format a number to 2 decimal places, e.g. num. toFixed(2) . The toFixed method takes a parameter, representing how many digits should appear after the decimal and returns the result.
The length of a number in base is the number of digits in the base- numeral for , given by the formula.
JavaScript Number toFixed() The toFixed() method converts a number to a string. The toFixed() method rounds the string to a specified number of decimals.
JavaScript numbers can be formatted in different ways like commas, currency, etc. You can use the toFixed() method to format the number with decimal points, and the toLocaleString() method to format the number with commas and Intl. NumberFormat() method to format the number with currency.

function pad(d) { return (d < 10) ? '0' + d.toString() : d.toString(); } pad(1); // 01 pad(9); // 09 pad(10); // 10 
String("0" + x).slice(-2); where x is your number.
