[rrd-users] Quick RPN question... (Square root in RPN?)

Hello all,

Am I right in thinking there is no easy way to do a square root in RPN?

I want to calculate a Standard Deviation of a set of values. Anyone done
this already?  

I want to use RPN because I'd like to superimpose the value of the Std Dev
on the graph of the normal values.

Or should I just use Perl and RRDs::fetch ?
