Docs on mode_declare and mode_identity



In mode_declare doc we see :

The arguments of mode_declare are pairs consisting of a variable and a mode which is one of
boolean, fixnum, number, rational, or float.

And in mode_identity doc we see :

The first argument to mode_identity is a primitive value mode name as given to mode_declare
(i.e., one of float, fixnum, number, list, or any)

Is it possible to know what are realy all the possible mode please?

Thank for help.
