[gnuastro-devel] [task #14340] Defining arbitrary variable and its value in FITS headers

[Mohammad Akhlaghi]

Follow-up Comment #5, task #14340 (project gnuastro):

Sorry, I meant the `gal_data_string_to_number' function of lib/data.c
<https://gitlab.com/makhlaghi/gnuastro/blob/datastruct/lib/data.c>. This
function will determine the type of a number written as a string and store it
automatically. So we won't need to explicitly keep the type of the variable in
the header keyword. If the returned pointer is NULL, we know the value was a
string and we can store it as such.

`gal_data_string_to_type' (that I mentioned in the previous comment), takes a
given type and reads the string in that, so it isn't useful for this job.
