title: Converting decimal with comma to binary
body: <p>I'm trying to convert decimal numbers with commas into binary. I've seen that if you have for example the number 5.2 in decimal you convert it to 101.10, since 5 is 101 and 2 is 10 but I've seen a method that I don't quite understand.</p>
  <p>For example, the number 93.3125 is 0000 0101 1101 0101. Why ?
  Are there other methods that help you transform decimals with comma into binary ?</p>
