title: Floating points multiplication
body: <p>I do not understand where to put the point after I multiply two floating point numbers.</p>
  
  <p>Let's say I have those two numbers:</p>
  
  <pre><code>float a = 0b11000011000100000100000...
  float b = 0b11000011000100000100000...
  </code></pre>
  
  <p>I know that I need to add the exponent and then to multiply the mantissas, but how do I know where to put the point in the end? How I decide where the point should be?</p>
