The status of fixed point is a Technical Report Type 2 (TR 18037), of
decimal floating-point is a draft TR Type 2 (DTR 24732). A TR is not a
standard or an amendment to a standard (so, for example, all uses of new
type specifiers and forms of constants should be diagnosed with
-pedantic), although depending on implementation experience it might be
considered for inclusion in future standard revisions.
