Get first number

I was wondering if it is possible to get the first number of a bigger number. For instance when a variable is 2674, that I can store the first number (in this case "2") and store it in another variable.

Thanx in advance!,

Just keep dividing it by 10 while it's greater than ten and then store the result as an integer.

 

var num = 2674;

var first = num.toString().substr(0, 1);

Code (javascript):

EDIT:

Or:

var first = num.toString()[0];

Code (javascript):

 

<script type="text/javascript">

var str="2674"
var shortStr = str.substring(0,1);

</script>

Code (markup):

Try above code. but keep it mind, var str should be string.
