If your machine supports the C data type long double and if you have a working libc you can enable long double precision for KCalc.
Here is what to do:
Check ../config.h and see whether
HAVE_LONG_DOUBLE is defined, that is, you should be able to locate a
line saying:
#define HAVE_LONG_DOUBLE 1
If you can't find such a line your system doesn't support long double IEEE precision.
Edit the files kcalctype.h,
configdlg.cpp, kcalc.cpp and
kcalc_core.cpp and remove the lines:
#ifdef HAVE_LONG_DOUBLE #undef HAVE_LONG_DOUBLE #endif
Recompile KCalc.
