Re: making a number from a decimal in XPath 2.0

  <xsl:function name="s:measure-block">

    <xsl:if test="$length-left > 0">
        <xsl:text>e</xsl:text>

Hi,

I'm trying to write an expression in XPath 2.0 to return me a string given a numeric argument as input, plus a parameter.

Call the parameter 'extent'. If $extent is 42, I'd like

(42) => e
(43) => ee
(84) => ee
(85) => eee

that is, as many 'e' as ceiling($arg div $extent)

But if I say

string-join((for $i in (1 to ceiling($arg div $extent)) return 'e'),'')

I get an error (Saxon 8.4) telling me I need an xs:integer as the second argument of the range expression "1 to ceiling($arg div $extent)", but I have an xs:decimal.

How do I make ceiling($arg div $extent) into an integer?

Alternatively, what neater ways are there to generate the string I need? Am I even approaching this the right way?

Cheers,
Wendell
