Definition in file Math.hpp.

◆ GEOGRAPHICLIB_WORDS_BIGENDIAN

#define GEOGRAPHICLIB_WORDS_BIGENDIAN 0

◆ GEOGRAPHICLIB_HAVE_LONG_DOUBLE

#define GEOGRAPHICLIB_HAVE_LONG_DOUBLE 0

◆ GEOGRAPHICLIB_PRECISION

#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.
