[Nexus] support for NaN (not a number)?

[Carlos Pascual Izarra]

Hello,
Can anyone point me to some documentation on how to handle NaN's in datasets?

My data comes from several counters that are read simultaneously from time to 
time. I want to save them in separate 1D Nexus datasets. Sometimes one 
counter may not return a reading, in which case I would like to insert a NaN 
marker in the given position of the dataset to signify it was invalid.
It should work for NX_FLOAT* and NX_*INT* data types

I am using the python binding.
Cheers,

Carlos
