There's a rank table sitting somewhere and I'm always looking for it. It would be really nice to add it to https://wiki.gnome.org/Projects/Vala/Manual/Attributes
If you want some more examples of numeric datatypes, I also have defined a couple in https://github.com/arteymix/numeric-glib/blob/master/src/numeric-glib-1.0.vapi 2016-12-05 13:16 GMT-05:00 Al Thomas <[email protected]>: > ________________________________ > > From: Guillaume Poirier-Morency <[email protected]> > > Sent: Monday, 5 December 2016, 17:30 > > Subject: Re: [Vala] VAPI-Bindings to obscure c-types. > > > You could also use a [FloatingType] declaration and not mess with > pre-processor directives. > > > [FloatingType] > > public struct dReal {} > > > Nice solution.
