view src/libxtract.c @ 113:72a9a393d5bd

- Fixed bugs in xtract_flatness(), or at least added necessary
documentation and error checking to avoid problems
- Added xtract_is_denormal() helper function and XTRACT_DENORMAL_FOUND
return code
- Replaced all instances of log, sqrt, exp etc. with respective
floating point counterparts (logf etc.)
- Added check for architecture endianness to configure script
- Bug fix to PD example, now no longer crashes if no arguments are
given
- Minor documentation updates
