title: What is the difference between float and double?
body: <p>I've read about the difference between double precision and single precision. However, in most cases, <code>float</code> and <code>double</code> seem to be interchangeable, i.e. using one or the other does not seem to affect the results. Is this really the case? When are floats and doubles interchangeable? What are the differences between them?</p>
