 Floating Point 
  It explains the binary representation of these numbers, how to convert to decimal from floating point, how to convert from floating point to decimal, discusses special cases in floating point, and finally ends with some C code to further one's understanding of floating point. 
  The single precision floating point unit is a packet of 32 bits, divided into three sections one bit, eight bits, and twentythree bits, in that order. 
  The answer is that there are special cases of floating point numbers, specifically when the exponent field is all 1 bits (255) or all 0 bits (0).
