Macro Definition Documentation

GEOGRAPHICLIB_CXX11_MATH

#define GEOGRAPHICLIB_CXX11_MATH   0

Are C++11 math functions available?

Definition at line 35 of file Math.hpp.

GEOGRAPHICLIB_HAVE_LONG_DOUBLE

#define GEOGRAPHICLIB_HAVE_LONG_DOUBLE   0

Definition at line 44 of file Math.hpp.

GEOGRAPHICLIB_PANIC

#define GEOGRAPHICLIB_PANIC   false

Definition at line 87 of file Math.hpp.

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.
