Subject: [Zope] Square Roots... Please help sqrt(x)


To anyone who may be able to help,

I need to calculate the distance between two zip codes and all is 
working except for the square root part.

I have been trying to use

<dtml-var expr="_.sqrt(x)">

to get the square root of x.  But it does not work and reports an 
attribute error.  I have used the _.int(x) with no problem and dis 
notice the sqrt() is in the Math Library.  Is there additional syntax to 
access this function?  I searched and googled and found everything but 
an example in DTML of how to use sqrt().

Thanks,
Richard
