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"). Michael Kay _____ From: www-ql-request@w3.org [mailto:www-ql-request@w3.org] On Behalf Of Stéphane Mbaye Sent: 23 September 2004 16:34 To: XQuery 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?
