[svn-r20384] Purpose:
Fixed Bug 2184 - GMQS: h5diff - incorrect calculation code for --use-system-epsilon option Description: Merged from HDF5 1.8 branch r20369. Fixed h5diff for --use-system-epsilon option: the calculation changed from ( |a - b| / b ) to ( |a - b| ). This was decided for better performance and was corrected only in HDF5 trunk, so 1.8 got updated. Also comments for equal_XXX() function were updated correctly. Also help page and RM got updated correctly. Also add test cases for testing the differences w/wo the option. Tested: jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE)

number.
-p R, --relative=R Print difference if (|(a-b)/b| > R), R is a positive
number.
- --use-system-epsilon Print difference if (|a-b| > EPSILON),
- where EPSILON (FLT_EPSILON or FLT_EPSILON) is the
- system epsilon value.
- If the system epsilon is not defined, use the value
- below:
+ --use-system-epsilon Print difference if (|a-b| > EPSILON), EPSILON is
+ a system epsilon value.
+ The system epsilon values are defined as below:
FLT_EPSILON = 1.19209E-07 for float
DBL_EPSILON = 2.22045E-16 for double
- -d, -p, and --use-system-epsilon options are used for
- comparing floating point values.
- By default, strict equality is used. Use -p or -d to
- set specific tolerance.
--exclude-path "path" Exclude the specified path to an object when
comparing files or groups. If a group is excluded,
all member objects will also be excluded.
