How do I select the nth digit in a large integer inside javascript?

Question

When I want to select the nth character, I use the charAt() method, but what's the equivalent I can use when dealing with integers instead of string values?

Answer 1

Use String():

var number = 132943154134;

// convert number to a string, then extract the first digit
var one = String(number).charAt(0);

// convert the first digit back to an integer
var one_as_number = Number(one);
