### Dimensions

The maximum number of dimensions supported by the GIO library, including the GDF FITS converter is now coded as a unique parameter named `GDF_MAXDIMS`. It has been increased from 4 to 71 between the two GDF versions. The SIC arithmetic engine has been prepared during the summer 2011 to be able to deal with such data cubes.

In the GDFV1, the number of elements per dimension and the total number of elements in the cube were stored in a standard integer, limited to . In the GDFV2, these elements are now stored as long integers (under 64 bits machines) and are now limited to .
