Don't do that! Instead, write

<xsl:variable name="gearMid" select="round(count(//rec_gear_sec/*) div 2)"/>

You want a number, not a result tree fragment containing a text node whose
string value is the decimal representation of a number. You also want to
avoid writing three lines of code that give you roughly what you want when
you could write one line that gives you exactly what you want.
