Hello all,

Performing this query...

xquery version "1.0";

declare namespace tst="http://test.racspace.com";

declare function tst:factorial ($input as xs:integer) as xs:integer {
    let $result := tst:multiply(1 to $input)
    return $result
};

declare function tst:multiply ($inputs as xs:integer*) as xs:integer {
    let $mid := count($inputs) div 2
    return if (count($inputs) eq 1) then $inputs[1] else
                              tst:multiply($inputs[position() <= $mid]) *
                              tst:multiply($inputs[position() > $mid])
};

let $inputs  := tokenize(normalize-space(/factorials),' ')
let $outputs := for $i in $inputs return xs:string(tst:factorial(xs:integer($i)))
       
return string-join($outputs, '&#x0a;')

on this input:

<factorials>
    10 20
    30 40
    50 60
    600
    1000

</factorials>​

Both Saxon and XQilla return the answer below, but BaseX says:

Stopped at /Users/jorgew/factorial/factorials.xq, 14/74:

[FOAR0002] Value out of range: 859541760 * 235989936000.

when I run via the cli like this :  basex -X -i factorial.xml factorials.xq

Thoughts? 

Thanks,

-jOrGe W.
