decimal number to binary number ?

[baby_annie]

In ActionScript, I can use parseInt to convert binary num to decimal number. But how can I convert decimal number to binary number? I try find in AS dictionary but there isn't result.
I have an input textfield to enter the decimal number, and an other to display the binary number.
Please tell me how...Thx U,

Here is a quick and crude method to convert a decimal number to a binary string in Flash MX:

// convert decimal number to binary string
function dec2bin(iNumber) {
	var bin = "";
	var oNumber = iNumber;
	while (iNumber>0) {
		if (iNumber%2) {
			bin = "1"+bin;
		} else {
			bin = "0"+bin;
		}
		iNumber = Math.floor(iNumber/2);
	}
	// left pad with zeros
	while (bin.length<15) {
		bin = "0"+bin;
	}
	return bin;
};

Found this thread while searching for a better version than what is posted above.

here's one, but I just came up with it so it could very easily be very wrong I did some tests, though, and it seemed to be accurate.

[edit]seems to be right because its about the same as yours, jtarbell, just a bit slimmer[/edit]

PHP Code:

function dec2bin(num) {
    var bin = "";
    while (num) {
        bin = num % 2 + bin;
        num = Math.floor(num / 2);
    }
    return (bin) ? bin : 0;
}
trace(dec2bin(60));

createTextField("Decimal", 10, 25, 25, 525, 20);
Decimal.text = "ten";
Decimal.type = "input";
createTextField("Binary", 20, 25, 75, 525, 20);
Binary.text = "two";
Binary.wordWrap = true;
Decimal.onChanged = function(){
	var numbr = parseInt(this.text);
	Binary.text = numbr.toString(2);
}

Number.toString - thats a new one for me! Thanks Pixelwit. Silly that I didn't know that.

Still, I enjoyed figuring that out. I'm trying to learn some math again. I wish we had all these math websites back when I was in Geometry and Trig in High school.
