Created attachment 62938 [details] code for IMCOT, IMCSC, IMSEC, IMTAN, IMSINH, IMCOSH, IMSECH, IMCSCH The origin of this work is in AOO issue id=111609. It is integration in AOO trunk with revision r1348096. It implements the imaginary functions IMTAN, IMCOT, IMSEC, IMCSC, IMSINH, IMCOSH, IMCSCH, IMSECH. Those are defined in ODFF, but not implemented yet. I have now transformed it to the attached patch, so it is applicable to LibreOffice. If you like it, you can use it immediately, without waiting for an AOO release. [I have sent it already to libreoffice@lists.freedesktop.org, but it seems the mail was overseen.]
Sometimes a review takes a day or two ... Thanks! Great patch! *** This bug has been marked as a duplicate of bug 51017 ***
