title: Ruby Sleep method
body: <p>I'm working on a geocoding piece/sidekiq job in a Rails/Ruby app.  So basically when we hit the Google API we sleep for 1 second to avoid the Google API query limit.  But I want to push the envelope and speed up processing a bit taking into account AR and SQL time.  So I'm trying to figure out how to sleep for 3/4 of a second.</p>
  
  <p>Can I just do sleep .75 or do I need to do some sort of math on sleep like sleep(1.0 / ??).</p>
  
  <p>Not sure if sleep can take a float like .75 or not.  Any thoughts on this?</p>
