[Exist-open] Converting values using xs:long

[Eugene M. <ema...@gm...>]

Hi,

I've got some data with some millisecond values that are like the following:

<longTest>
    <creationTimeMillisecs>1241535599263</creationTimeMillisecs>
    <creationTimeMillisecs>1241121151513</creationTimeMillisecs>
    <creationTimeMillisecs>1241727627917</creationTimeMillisecs>
    <creationTimeMillisecs>1241535651217</creationTimeMillisecs>
</longTest>

As part of a query I wanted to find the max of these. The result would come
out in scientific notation, stuff like: 1.241727627917E12

The output needed to be in a regular integer format though, like the
originals. Applying xs:long to the value I get an error:

FOCA0003: Value is out of range for type xs:integer

Looking at the code, it looks like all the Integer conversions from Doubles
are checked against Integer.MAX_VALUE, then converted to longs. Is there
some reason it is not checking against Long.MAX_VALUE?

The code I'm talking about is line 177 of DoubleValue.java from:

http://exist.svn.sourceforge.net/viewvc/exist/trunk/eXist/src/org/exist/xquery/value/DoubleValue.java?revision=8202&view=markup

See ya,
Eugene
