Re: [MarkLogic Dev General] Unexpected Failure Doing Math on Durations (ML 8.0-3.2

Hmm. Apparently I have to set $div to xs:double. That still seems unnecessary 
and feels like a bug.

Cheers,

E.

(ML 8.0-3.2)

In my xquery I’m doing this:

let $total := xs:dayTimeDuration("PT6M38.33S")
let $fastest-three := xs:dayTimeDuration("PT4M6.258784S")
let $div := ($fastest-three div $total)

 return ($div)

Which returns:

0.6182280621595159793

If I then try to multiple $div by 100 (to get a percent) I get decimal 
overflow:

[1.0-ml] XDMP-DECOVRFLW: (err:FOAR0002) $div * 100 -- Decimal overflow

Which is not at all expected.

I also noticed that ML 8 does not appear to support the XQuery 3.x 
two-argument round() function, e.g., round($div, 2).

Why am I getting a decimal overflow here?

As a test I tried doing the same thing with Saxon 9.7 and XSLT 3:

http://www.w3.org/1999/XSL/Transform";
  xmlns:xs="http://www.w3.org/2001/XMLSchema";
  exclude-result-prefixes="xs"
  version="3.1">
  




  div: 
  $div * 100: 
  round($div, 2) = 

  


Which produces:


  div: 0.61822806215951597921
  $div * 100: 61.822806215951597921
  round($div, 2) = 0.62

Thanks,

Eliot
