| 18 | # It isn't necessary to chose fixed or floating point for the APIs because the |
| 19 | # simplified API doesn't need fixed or floating point numbers. It is necessary |
| 20 | # to chose an internal math implementation. The default (because of 'everything |
| 21 | # = off') is fixed point - turn the floating point implementation on if you have |
| 22 | # hardware floating point or prefer your software floating point implementation. |

| 31 | # changed to match common hardware formats. |
