Hello,

I'm trying to make a small template that concisely implements atan2, but returns the values in degrees and handles the case where DX is zero. So far, I have:

<xsl:template name="my_atan2"> <xsl:param name="dx" /> <xsl:param name="dy" />

<xsl:variable name="rad" > <xsl:choose> <xsl:when test="dx != 0"> <xsl:value-of select="exsl:atan2(dx, dy)" /> </xsl:when>

<xsl:when test="(dx = 0) and (dy &gt; 0)"> <xsl:value-of select="$my_pi" /> </xsl:when>

<xsl:when test="(dx = 0) and (dy &lt; 0)"> <xsl:value-of select="$my_pi * 3" /> </xsl:when> </xsl:choose> </xsl:variable>

<xsl:choose> <xsl:when test="$rad &lt; 0"> <xsl:value-of select="($rad * 180 div $my_pi) + 360" /> </xsl:when>

<xsl:otherwise> <xsl:value-of select="($rad * 180 div $my_pi)" /> </xsl:otherwise> </xsl:choose> </xsl:template>

Is there a way to express this in only a few lines without all the verbosity?
