2?'s: Rounding and Printing 1

[jonu61]

Hi,

I have two questions. I have some variables that I need to round to the 4th decimal place. The number can range from any where between 1 through 100000. Is there anyway to round these numbers to the 4th decimal place?

Next question,
I have a print button on a frame. I want the frame to print in landscape. I have it setup now where you can print it and set whether to print in portrait or landscape manually. Is there anyway to set this up where it will automatically print in landscape? I am currently using the code:

on (release) {
print(this,"bmovie");
}
Thanks,
Jon

You can round to specific places by multiplying the number, rounding then dividing again. Like this:

function round(num) {
	num *= 10000;
	num = Math.round(num);
	num /= 10000;
	return num;
}
//
trace(round(0.123456789));
