The patch is attached. Should I upload it to Trac, and reopen ticket #305? For the case of C, C99 complexes will be automatically used ONLY if _Complex_I is defined... of if the user explicitly pass "-DPYX_CCOMPLEX=1" at C-compile time (or a Cython-included C header #define PYX_CCOMPLEX=1), or if the directive "ccomplex=True". I'm still in doubt about how to handle 'ccomplex=True'... Should it just enable by default using "#define PYX_CCOMPLEX=1", or actually impact in code generation (as currently does)... Ah! I forgot... I do not know how to implement z.conjugate(); the C/C99/C++ support is there though... BTW, GCC seems to accept "~z" for complex conjugation (no idea if it is C99-standard or a GCC-extension)... Perhaps Cython should accept this (non-Python) syntax? I think it is nice. -- Lisandro Dalcín --------------- Centro Internacional de Métodos Computacionales en Ingeniería (CIMEC) Instituto de Desarrollo Tecnológico para la Industria Química (INTEC) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) PTLC - Güemes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594
