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

I also noticed that ML 8 does not appear to support the XQuery 3.x two-argument round() function, e.g., round($div, 2). Why am I getting a decimal overflow here? As a test I tried doing the same thing with Saxon 9.7 and XSLT 3: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; exclude-result-prefixes="xs" version="3.1"> <xsl:template match="/"> <xsl:variable name="total" as="xs:dayTimeDuration" select='xs:dayTimeDuration("PT6M38.33S")'/> <xsl:variable name="fastest-three" as="xs:dayTimeDuration" select='xs:dayTimeDuration("PT4M6.258784S")'/> <xsl:variable name="div" as="xs:decimal" select="$fastest-three div $total" /> <result> div: <xsl:value-of select="$div"/> $div * 100: <xsl:value-of select="$div * 100"/> round($div, 2) = <xsl:value-of select="round($div, 2)"/> </result> </xsl:template> </xsl:stylesheet> Which produces: <result> div: 0.61822806215951597921 $div * 100: 61.822806215951597921 round($div, 2) = 0.62</result> Thanks, Eliot -- Eliot Kimber http://contrext.com _______________________________________________ General mailing list [email protected] Manage your subscription at: http://developer.marklogic.com/mailman/listinfo/general _______________________________________________ General mailing list [email protected] Manage your subscription at: http://developer.marklogic.com/mailman/listinfo/general
