Re: [xsl] Saxon Div Issue

["Mailing Lists Mail daktapaal@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

THe problem is , I dont know what will come in the $num. It is an
xpath. It comes from an XML element.

SO sometimes, the element contains 988, and sometimes it contains 98.8
.. so my pseudo code actually is :"

$num = /xpath/num
var result = $num div 100

I wouldn't know if it will be a double that I will be a decimal.
