Hello Withers:

Small correction and I think it is obvious.

#set ($pc = ($part * $maxwidth) / $total) 

Should be replaced by 

#set ($nw = ($part * $maxwidth) / $total)

Regards,
Mathi.

Hmmm.  Could this be something as simple as integer arithmetic?  Have
you tried:

#set ($pc = ($part * $maxwidth) / $total)

Subject: Double-Calculations in Velocity

Hy,
I wrote this macro:
=====
#macro ( pollbar $total $part $maxwidth $color )
	#set($pc=$part/$total)
	#set ($nw=$pc*$maxwidth)
	<img src="/images/poll/color${color}.gif" width="$nw" height="5"
xxx="$pc" />
#end
=====

For some values this works but for the most $nw is 0 afterwards because
$pc is 
0. Is this my mistake or is velocity unable to calc in double or float?

Thanks
TO
