These are conventional names of the values infinity, minus infinity, and
not-a-number which are defined in the value space of xs:float and xs:double.
They are not constants in the language, and must be constructed using
expressions such as xs:float("INF").

Subject: INF and NaN

Hi,

the « Functions an Operators » specifications frequently refer to INF and
NaN such as they were predefined constants of the language. However, they
are apparently not part of the XQuery or XPath grammars. Is “fn:round(INF)”
a correct syntax such as presented in the specs?
