#def displayfloat($a)
$("%.2f"%$a)#slurp
#end def
#set showfloat = self.displayfloat

 str(compiled_tmpl)
  File "/usr/lib/python2.5/site-packages/Cheetah/Template.py", line 997, in
__str__
    return getattr(self, mainMethName)()
  File "<string>", line 3514, in respond
NotFound: cannot find 'showfloat' while searching for 'showfloat'
