Question

This code:

function foo(){
    var x = 5;
    var y = "8.8";
    var exp1 = typeof(2 * y);
    var exp2 = typeof(x + y);
    var exp3 = typeof(parsefloat(x + y));
    var exp4 = typeof(x + parsefloat(y));
    var exp5 = typeof(x + parseint(y));
    var exp6 = typeof(x-y);
    var exp7 = typeof(x*y);
    alert( exp1 + ", " + exp2 + ", " + exp3 + ", " + exp4 + ", " + exp5 + ", " + exp6 + ", " + exp7 + "." );
}

Gives me an “object expected” error on the line starting with var exp3, character 2.

Edit:

Not necessary, but why is it an error on character 2?

Answer 1

JavaScript is case-sensitive. Use parseFloat and parseInt.
