convert int to hex

[jon]

Hi, my maths skills arent up to this. I need to convert an interger to a hexidecimal value.

like -1 to a value like 0xFFFE (not that that is correct)

Hope you can help

In ffish script you can use

var i = -1324;
var ihex = i.format("0X%08X");
trace(ihex);

However, it is not a standard method of Javascript. In javascript you can try

function integerToHex(number) {
	var hex_chars = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'];
	// the output, supports only 32-bit integers
	var out = ['0', '0', '0', '0', '0', '0', '0', '0'];
	var len = out.length;
	for (var i = 0; i < len; i++) {
		var n = number >> 4;
		out[len - i - 1] = hex_chars[number - (n << 4)];
		number = n;
	}
	
	return "0X" + out.join("");
}

trace(integerToHex(-1324));
