title: Converts two 16 bits word to float in python
body: <p>I've written a script that reads from a modbus channel and returns tuples of words (16 bits). 
  I need to translate them into decimal numbers, how can I do it?
  I've been reviewing the 'struct' python package, however, I'm not sure how to use it to achieve this.</p>
  
  <p>EDIT: 
  I'll give an example. Following the documentation, (43H, C8H) should be translated into 400 (decimal).</p>
  
  <p>However, the modbus package returns a python tuple of two integers, like (1000, 60450).</p>
  
  <p>BR,</p>
