I have a number which represent time and I need to convert this number into string.
Like n = 800 , it represent time = 8:00
Currently I am doing this:
n = 800;
string time = '' + n/100 + ' : ' + n % 100 ;
but time
become 8 : 0
but I want to minutes in two digit format like 8 : 00
Anybody please help me there?
var n = 800;
var hours = Math.floor(n/100);
var minutes = ('0' + (n%100)).slice(-2);
var time = hours + ':' + minutes;
Note the rounding on hours as well, otherwise you could end up with something like "8.56:56".
If all you are trying to do here is insert a colon before the last two digits you can just do a string replace:
var time = ("" + n).replace(/(\d\d)$/,":$1");
Or slice out the hours and minutes and concatenate with a colon:
var time = "" + n;
time = time.slice(0,-2) + ":" + time.slice(-2);
Just a shortcut solution :P
var a = 800;
var b = a.toString();
var first = b.replace(b.substring(b.length - 2),":"+b.substring(b.length - 2));
