The C standard uses (and also defines) the word NaN as a generic
term applicable to floating-point representations in general.  In
section 5.2.4.2.2 paragraph 3, the C standard says this

    A /NaN/ is an encoding signifying Not-a-Number.

with the slant characters meaning italics, which indicates a
definition.  The same paragraph gives generic definitions for
the more specialized terms "quiet NaN" and "signaling NaN".

There is a footnote that mentions the IEEE floating-point
standard, but makes clear that terms for the various kinds of NaN
can refer to values in other floating-point systems that have
similar behavior.
