You may want to try looking at compiler listings for unoptimized (or
optimized) COBOL code using COMP-1 (short float) or COMP-2 (long
float).

By using the various compiler options (to choose between the various
types of floating point numbers) and doing arithmetic and/or moving
floating point number to Binary and/or Packed number you will be able
to generate a quick tutorial for yourself.

The same can be done with the C/C++ compiler other other compilers on
your system.
