flag used as third parameter for open_data, indicates how data files are searched AS_DATA_ONLY: search only in the data directories, not in the current working directory (default) AS_DATA_OPTIONAL: same as AS_DATA_ONLY, except that the precense of the file is optional AS_DATA_LOCAL: search in data directories first, then in the current working directory AS_LOCAL_DATA: search in the current working directory first, then in the data directories AS_LOCAL_ONLY: search in the current working directory only versions with _TRY appended have the same meaning, except that they don't abort

define routines for setting single and double precision signaling NaN The bit pattern for an SNaN is implementation defined, but this should work on most modern CPU's. The system definition is preferred, so in C++ this should be replaced by numeric_limits<TYPE>::signaling_NaN()
