Using round

Hi all,

I wonder if anyone is using the round function in commcare.

I am trying this

        <bind nodeset="/data/talla" type="xsd:double" constraint=".&gt;= 60 and .&lt;= 200" jr:constraintMsg="jr:itext('talla-constraintMsg')" required="true()" />
        <bind nodeset="/data/roundt" type="xsd:double" calculate="round(/data/talla,2)" />

I am getting this:

internal error handling request: <type ‘org.javarosa.xpath.XPathUnhandledException’>: org.javarosa.xpath.XPathUnhandledException: XPath evaluation: cannot handle function ‘round’

In both, cloudcare and commcare ODK,

Any ideas?

Thanks in advance,

William

William,

I’m not sure that we currently implement the round() function
https://confluence.dimagi.com/display/commcarepublic/List+of+xpath+functionsbut
in use it is identical to the

int()

function, so you should be able to just use that as a replacement. You’ll
need to pass it one argument, though, rather than two. Is the “2” in that
function call attempting to do something?

i assume it means ‘round to 2 decimal places’.

you could do this with int(100*/data/value + .5)/100

Yes Drew,

I need two decimal places, and I think I could make it work with
this,

I asked because ODK supports that function:

Thanks

William,

Thanks for the heads up! We’ll do our best to integrate these functions to
maintain compatibility in the future.

Sorry about any difficulty, and hopefully the workaround fits your needs.

Hi Clayton

Using int() wit the suggested approach works well.

Thank you all guys for being so supportive,

William
