HDP dumpsds question

Greetings list,

I'm using HDP to dump MERRA HDF files to ascii. I've noticed an issue, one variable (RH/relative humidity, unit is percent) seems to output an incorrect value.

Using HDFView in tableview and in 'table -> export data to text file' output I see a value <1.784414E-6>. The corresponding value from the 'hdp dumpsds' result is <0.000002>. Might this be an error? Is there a way to use HDP to obtain the same precision in the dumped ascii as is in the HDF file?
