Hello Ben,

this is quite typical, as in binary would use often more bits for storage. In 
ascii each letter/number is a byte, so a float can be just a few bytes, but in 
binary you have at least four if not eight depending on your machine .

So often a formatted ascii with floats using only a few digits is smaller than 
the binary.

'hope this makes sense,

best wishes,

Joerg

Dear netcdf users,

I have data I want to convert to nc format.
This data is integers, floating point numbers and text.

I created a dummy nc file containing text and I realize the binary file is 
larger that the text file.
How come ?

See by yourself: convert the joint file to binary using
ncgen -b foo.nc.txt

Thank you in advance for your help.
Ben
