Specifying output format with save()

[Alberto Luaces]

Hello,

is there any way to specify a desired format (width, decimal places)
when saving variables with save()?

My problem is that I want to read the file at a later stage with
Fortran, and it does not allow that the numbers have different widths,
including spaces.

I read about save_precision(), but it seems that only decimal places can
be specified.

I think I could do what I want with fprintf, but I would like to know if
there is a much more direct solution using save().

Thanks,
