How to pick the last digit of a number in Actionscript 3

Question

I have a variable with some value (var qtdd = 758) within a function and would like to take only the last digit of this variable, in case the number 8. Does anyone know how to do this in Actionscript 3?

Follows the code:

this.addEventListener("tick", capta_x.bind(this));

function capta_x() {

    var qtdd = 758;

}

Answer 1

Divide the number by 10 and take only the rest of the division, but as the % serves precisely to return the rest of the division, the first calculation and unnecessary:

function capta_x() {
    var qtdd = 758;
    return qtdd % 10;
}

Answer 2

Another way, in AS3 :

var qtdd = 758;
var qtddString:String = qtdd.toString(); // converte para string
var ultimoChar = qtddString.charAt(qtddString.length - 1)); // pega o ultimo character e retorna "8"
var ultimoNum = Number(ultimoChar); // converte para numero e retorna 8
