Close, but it's the chapter above your link:

If anyone's interested in another explanation of floating point values, there's a nice article by Fabien Sanglard, and extract from his book about Wolfenstein. The Intel chips use IEEE 754 but it's close enough to the CPC's format to help in understanding how floating point works. There's a few omissions in it but then it's not meant for a science paper.
