* This patch makes complex arithmetic in C and C++ more efficient, andschnetter2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | makes it much more convenient for C++, expecially when templates are used. The flesh functions for complex arithmetic are defined (not only declared) by including Complex.c from the header file cctk_Complex.h. They are declared "static inline", so the the compiler can inline them, but does not have to create an out-of-line copy for every source file. Complex.c is also compiled stand-alone without the "static inline" prefix, so that out-of-line copies exist as well. Add some new complex arithmetic functions, e.g. ComplexNeg to change the sign. Make some complex arithmetic functions more efficient by using algorithms from glibc. These algorithms are LGPL. They should be faster and/or more accurate than the existing implementations. For C++, define the usual arithmetic operators (+-*/ etc.) as inline functions calling the corresponding complex arithmetic functions. This makes it possible to use complex numbers in the same way as real numbers, which makes it possible to instantiate templates for both CCTK_REAL and CCTK_COMPLEX. This leads to much code reduction in Carpet. The patch also appends a type postfix to the names of math functions called in the inlined routines: 'f' for HAVE_CCTK_REAL4, nothing for HAVE_CCTK_REAL8, and 'l' for HAVE_CCTK_REAL16. This avoids compiler warnings about conversions from "double" to "float" which may lose significant bits. git-svn-id: http://svn.cactuscode.org/flesh/trunk@4418 17b73243-c579-4c4c-a9d2-2d5706c11dac
