I was quite excited to find this out!

Have you ever wanted to make a simple calculation for a template, like an addition or subtraction? Personally, I needed this many times and most of them I created a plugin for that. Today I discovered that that is unecessary. You can use the conditional to make simple calculations. For instance, lets suppose you want to display somewhere the userid of the current user, incremented by one. You could do this:
HTML Code:
<if condition="$nextid = $bbuserinfo['userid']+1"></if>
The next userid is $nextid.
This will display as (given that the userid of the user viewing is 1):
Quote:
The next userid is 2.
Of course the userid example is very simple, just to make you understand what I'm talking about.

Let me know if it helped you!

Is there a way we can use this to generate a random number and then test against it so that something happens only 1/X times?

Nope. The functions for random number generation aren't allowed in templates, so you have to use a plugin.
