I just noticed another angle issue: 19.171 draw:formula says: "sin(n) returns the trigonometric sine of n, where n is an angle specified in degrees" and similarly for cos. At least one implementation, LibreOffice writes: <draw:custom-shape draw:z-index="1" draw:style-name="gr1" svg:width="6.03cm" svg:height="4.064cm" svg:x="12.638cm" svg:y="2.656cm"><text:p/> <draw:enhanced-geometry svg:viewBox="0 0 21600 21600" draw:path-stretchpoint-x="10800" draw:path-stretchpoint-y="10800" draw:text-areas="?f3 ?f4 ?f5 ?f6" draw:type="round-rectangle" draw:modifiers="3600" draw:enhanced-path="M ?f7 0 X 0 ?f8 L 0 ?f9 Y ?f7 21600 L ?f10 21600 X 21600 ?f9 L 21600 ?f8 Y ?f10 0 Z N"><draw:equation draw:name="f0" draw:formula="45"/><draw:equation draw:name="f1" draw:formula="$0 *sin(?f0 *(pi/180))"/><draw:equation draw:name="f2" draw:formula="?f1 *3163/7636"/><draw:equation draw:name="f3" draw:formula="left+?f2 "/><draw:equation draw:name="f4" draw:formula="top+?f2 "/><draw:equation draw:name="f5" draw:formula="right-?f2 "/><draw:equation draw:name="f6" draw:formula="bottom-?f2 "/><draw:equation draw:name="f7" draw:formula="left+$0 "/><draw:equation draw:name="f8" draw:formula="top +$0 "/><draw:equation draw:name="f9" draw:formula="bottom-$0 "/><draw:equation draw:name="f10" draw:formula="right-$0 "/><draw:handle draw:handle-position="$0 top" draw:handle-switched="true" draw:handle-range-x-minimum="0" draw:handle-range-x-maximum="10800"/> </draw:enhanced-geometry></draw:custom-shape> In this the use of <draw:equation draw:name="f1" draw:formula="$0 *sin(?f0 *(pi/180))"/> seems to indicate that they use sin with arguments that are radians! I am not filing a JIRA issue since as in the other case I believe this to be simply an implementation bug. Andreas -- Andreas J.
