title: Reinterpret cast floating point number to integer
body: <p>This question is probably "unusual", but I need to cast a float <code>Number</code> to an integer <code>Number</code>, without modifying its binary representation.</p>
  
  <p>For example, the float <code>37.5</code> is represented by the bytes <code>0x42160000</code> (according to IEEE 754).
  I need to reinterpret <code>0x42160000</code> as an integer, i.e. the number <code>1108738048</code></p>
  
  <p>How do I do this? I'm thinking there could be some bitwise tricks to accomplish this?</p>
  
  <p>To be clear, I'm <em>not</em> looking for <code>Math.round</code> or <code>parseInt</code>.</p>
