#define GEOGRAPHICLIB_CXX11_MATH 0 |
#define GEOGRAPHICLIB_PRECISION 2 |
The precision of floating point numbers used in GeographicLib. 1 means float (single precision); 2 (the default) means double; 3 means long double; 4 is reserved for quadruple precision. Nearly all the testing has been carried out with doubles and that's the recommended configuration. In order for long double to be used, GEOGRAPHICLIB_HAVE_LONG_DOUBLE needs to be defined. Note that with Microsoft Visual Studio, long double is the same as double.
