Rhys,
It may be the case that your system epsilon is different from DBL_EPSILON.
Here is what I copied from h5diff UG for clarification:
-d D, --delta=D
Print difference if (|a-b| > D). D must be a positive number.
Can not use with '-p' or '--use-system-epsilon'.
-p R, --relative=R
Print difference if (|(a-b)/b| > R). R must be a positive number.
Can not use with '-d' or '--use-system-epsilon'.
--use-system-epsilon
Print difference if (|a-b| > EPSILON), EPSILON is system
defined value.
If the system epsilon is not defined,one of the following
predefined
values will be used:
FLT_EPSILON = 1.19209E-07 for floating-point type
DBL_EPSILON = 2.22045E-16 for double precision type
Can not use with '-p' or '-d'.
Thanks

'Afternoon,
Atop h5diff 1.8.5-patch1 I've noticed that comparing NaN against NaN
passes when using --use-system-epsilon. It fail when using
--delta=something.
Does --use-system-epsilon imply more than just --delta=DBL_EPSILON?
If so, please add that to the --help message.
