How to round a variable value to 2 digit in javascript

Question

Suppose,

a=0;

then the result should be 00

a=10
result=10

a=2
result=02

like all values needs to round in 2 decimal point. Note: No need to round the values having more than 2 digits.

Your code doesn't show decimal places. It appears you want padding? — Erik Philips, Jan 02 '18 at 07:40

Are you looking for something like that;

var int = 3;
var intStr = ("0" + int).slice(-2);
Output : 03

For any number of digits

var temp = 9;
if(temp < 10){
var temp = ("0" + temp).slice(-2);
}

For only two digit simply append zero if it is one digit number :-

var temp = 19;
if(temp < 10){
var temp = "0" + temp;
}
