Changes default precision from 1/32" to 1/16" for cleaner measurements and
simplifies output by omitting unnecessary fraction components.
- Change default precision from 32 to 16
- Return whole numbers without "-0/N" suffix when fraction rounds to zero
- Update documentation to reflect new default precision
This makes measurements more readable (e.g., "12" instead of "12-0/16") while
maintaining sufficient precision for typical woodworking applications.
