Shared-code and automatic ability to use an attached numeric processor.
When you use the math libraries, your application does not have to contain
the code to do the math--your application will be smaller.  As an 
additional benefit, when you add a math co-processor the libraries
will use them without any change to your executable.

Lattice C can call the math libraries if you set the correct flags.
See the Lattice manual for information on "lc", then look for the
"-f" flag.
