19# It isn't necessary to chose fixed or floating point for the APIs because the
20# simplified API doesn't need fixed or floating point numbers.  It is necessary
21# to chose an internal math implementation.  The default (because of 'everything
22# = off') is fixed point - turn the floating point implementation on if you have
23# hardware floating point or prefer your software floating point implementation.
