[Exist-open] Bug in fn:round()? + speed/range index issue

[<sju...@ko...>]

Hello,

fn:round() returns what looks like xs:decimal even though it should(?)=20=

return an integer, at least when looking at the examples in the XQuery=20=

function specs:

> =95 	fn:round(2.5) returns 3.
> =95 	fn:round(2.4999) returns 2.

Here's my own code:

   let $r :=3D document('/db/ordbase/terms/SD-terms/termcenter.xml')
     //entry/@id
   return round(max($r))

This always returns values of the form '1234.0' instead of the expected=20=

'1234'. Or is there something I have misunderstood?

fn:max() takes quite some time in the above example, on average 2,5=20
seconds. This is true even though I have the attribute in question=20
indexed as an xs:integer:

<create path=3D"/termCenter/entry/@id" type=3D"xs:integer"/>

There are 12235 instances of this attribute. The speed is roughly the=20
same without the range index, whereas I would expect the range index to=20=

improve the response time also in this case.

Sjur
