Math Problem

[MVied]

Okay, so I'm writing an application. In this application there is a drop down with the selections 10, 20, 30, and so on to 100. This drop down controls the amount of times a loop will occur. Basically, every time the application gets to a loop that is 10% of the total amount of loops, I want it to echo out a small line. On the user end this outputs a small block in a progress bar.

For example if you choose 10, then every loops it would output a block on the progress bar to give us 100%.

If you choose 20, every 2 loops it would output a block on the progress bar to give us 100%.

The easy way out would be to make a huge case select of if, elseif statement, but that's not what I want to do.

As an example, if you choose 10 ($amount = 10), it works correctly. $i is the increment of the loop.

echo ($i % ($amount / 10) == 0) ? "<div class=\"load\"></div>" : "";

I know that's very confusing, but hopefully someone can understand and give me some mathematical help. :P

I have had to do similar things in the past and I find division and rounding to be the answer. An example is as below:

$loop=0;
while ($loop<=100)
	{
	$val=$loop/10;
	if ($val==round($val))
		{
		echo ($i % ($amount / 10) == 0) ? "<div class=\"load\"></div>" : "";
		}
	$loop+=1;
	}

Hope that helps to answer your question.

Well, your solution didn't work for me, but it got me thinking and now my code works. :D

Soon I'm going to post it in the Web Developer's Lounge. It'll be something everyone wants. ;)

I don't know if round would be necessary since 10, 20, 30..., 100 are all % 10 evenly. :-/

And I don't see why this code:

echo ($i % ($amount / 10) == 0) ? "<div class=\"load\"></div>" : "";

wouldn't work. :-/

Can you post the rest of your code?

Oh, you got it, OK.

Basically the problem was $i starting off as 0. This threw it off completely. I used $n to start as 1 and count (because I use the $i for more than just an increment).

I'll be posting this project soon. I know you'll like it R0b ;)
