Danke Alex :)

  the prints were more of an example. In the 'real' world, 
  the data is read in from a file with readu and is an array
  of float variables. I want to perform the following maths 
  in double but with the cast to double I already introduce 
  'pretty random digits to the right', as you say.
  I'ld really like to avoid calling something like double(string(a))
  for some large array...

Any ideas?

Schönes langes Wochenende,
