How to display the average value of two field in postbit

[theduyet]

Asume that my user table has two columns .One is votetotal and the other is votenum.I can print the value of them in postbit just using : post[votetotal],and post[votenum].However,i only want to print the average value of them when votenum>0 and 0 when votenum<0.
How can i do that?

Are you using a plugin to get the votetotal and votenum? If so, just add the php to get the average. If you aren't using a plugin, you may be able to do the math in the template just take a look at this article - Perform simple calculations inside templates!. If you can't do it in the template, then you'll have to add a plugin.

I tried to do it in the templates.

<if condition="$post[votenum]!=0">
<if condition="$rateave = $post[votetotal]/$post[votenum]"></if>
$rateave
</if>

It's okey.However the result is not good looking.
Example if the votetotal is 11,the votenum is 3.It will print 3.6666666666667 .
I just want to get the value 3.67 or 4.

--------------- Added [DATE]1245564040[/DATE] at [TIME]1245564040[/TIME] ---------------

<if condition="$post[votenum]!=0">
<if condition="$rateave = $post[votetotal]/$post[votenum]"></if>
<if condition="$rateave >0 && $rateave < 1.5"><if condition="$rateave1=1"></if></if>
<if condition="$rateave >=1.5 && rateave< 2.5"><if condition="$rateave1=2"></if></if>
<if condition="$rateave >=2.5 && rateave<3.5 "><if condition="$rateave1=3"></if></if>
<if condition="$rateave >=3.5 &&rateave<4.5"><if condition="$rateave1=4"></if></if>
<if condition="$rateave >=4.5 "><if condition="$rateave1=5"></if></if>
$rateave1
</if>

Because the maximum rated score is 5 (5 star)I tried to use this and it works.
However,if i want to use the plugin,how can i do that?
Thanks.

You would write the php to do this and probably use a hook location like postbit_display_complete. Plugin System
