    how to find if i is an even number?

    how can i find out if a variable which name is i is an even number?
    Could i divide i by two and if the result has no decimal places its an even number.

    anybody have any code for this?

    Two possibilities:

    Code:
    var num = 41;
    
    if (num & 1 == 1) {
    	alert('is uneven');
    }
    
    if (num % 2 != 0) {
    	alert('is uneven');	
    }
