Hi,
I have found the following behaviour in BaseX 9.0:
"Infinity" cast as xs:float (: INF :) "-Infinity" cast as xs:float (: -INF :) "infinity" cast as xs:float (: [FORG0001] Cannot convert xs:string to xs:float: "infinity". :) "Infinity" cast as xs:double (: [FORG0001] Cannot convert xs:string to xs:double: "Infinity". :) "-Infinity" cast as xs:double (: [FORG0001] Cannot convert xs:string to xs:double: "-Infinity". :)
From my reading of Functions and Operators 3.1, and XML Schema 1.1 Part 2
Datatypes, "Infinity" and "-Infinity" are both invalid values for xs:float (like with xs:double) -- they should only be "INF" and "-INF".
Kind regards, Reece H. Dunn
