Code:
awk -v min=0.001 -v max=1000.0 '{
  $1 = $1 # the same formating for all lines 
  for (i=1; i<=NR; i++) 
    if ($i)                 
      if ($i < min) $i = min     
      else if ($i > max) $i = max
  print     
}' INPUTFILE

You can change OFS and OFMT variables to format output of values.
