I could not find this function in man pages either and also http://en.cppreference.com/w/c/numeric/math/exp does not list it. log10 exists but did not see and kind of exp10. Could you have been thin of a macro you saw in an app? the only ref I found from searching ports/math was: /usr/ports/math/ldouble/files/i386-makefile-patch: exp10l.o exp2l.o expl.o expx2l.o fdtrl.o gammal.o gdtrl.o igamil.o igaml.o \ > > #include <math.h> > > int main(int argc, char** argv) > { > (void)argv; > return ((int*)(&exp10))[argc]; > } > > tried compiling it with clang: > clang++ test.cpp -o test -lm > test.cpp:7:17: error: use of undeclared identifier 'expf10' > return ((int*)(&expf10))[argc]; > ^ > 1 error generated. > > tried with gcc: > gcc test.cpp -o test -lm > test.cpp: In function 'int main(int, char**)': > test.cpp:7:17: error: 'expf10' was not declared in this scope > return ((int*)(&expf10))[argc]; > > Does FreeBSD math.h have expf10 and if so, how do I link against it? > _______________________________________________ > freebsd-ports@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-ports > To unsubscribe, send any mail to > "freebsd-ports-unsubscr...@freebsd.org" -- Best Regards.
