The NUG presents the formulae for packing/unpacking on this page which reads
Each variable with packed data has two attributes called scale_factor and add_offset, so that the packed data may be read and unpacked using the formula:
> unpacked_data_value = packed_data_value * scale_factor + > add_offset
...
> packed_data_value = nint((unpacked_data_value - > add_offset) / scale_factor)
The > characters that immediately precede add_offset in both equations appear to be typos. I suggest deleting them.
