title: Letters within integers. What are they?
body: <p>This is an excerpt of code from a class I am working with in Java (below). Obviously the code is defining a static variable named EPSILON with the data type double. What I don't understand is the "1E-14" part. What kind of number is that? What does it mean?</p>
  
  <p>final double EPSILON = 1E-14;</p>
