Re: [NTG-context] Add labels to a grid (Metafun)

[Fabrice]

thank you very much Alain, I think I understood for the format "@d" but 
for other formats, I will need documentation.

it is a string format specifier such as "%g", "%f", "%d", ...
Since the % can sometimes cause problems being interpreted as a comment
character, it is usually replaced in Metafun by @, as in "@g".
