title: How to generate random numbers between 0.1 and 0.01
body: <p>I know its possible to generate integer random number using </p>
  
  <p><code>(rand() % (difference_between_upper_and_lower_limit)) + lower_limit</code></p>
  
  <p>I'm wondering if theres a way to generate a number between 0.1 and 0.01. 
  I've tried 
  <code>double speed =  (rand() % 10)/100;</code>
  But it always just gives me 0.0000000;
  Thanks in Advance!`</p>
