pd -lib gridflow

and put this external in your ~/.gridflow_startup :

GridFlow::FObject.subclass("atof",1,1) {
   def _0_symbol s
     m = /[-+0-9\.eE]+/ .match s.to_s
     send_out 0, Float(m[1])

This is a [atof] external which will extract the first numeric string in a 
symbol message and output the corresponding float.

note: I didn't test the above code, so if someone tells me it doesn't 
work, I'll correct the typos. (my computer just blew up so I don't have 
access to PureData at the moment)
