[xsl] XSLT verbosity (atan2)

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?
