## ◆ GEOGRAPHICLIB_AUXLATITUDE_ORDER

#define GEOGRAPHICLIB_AUXLATITUDE_ORDER

Value:
(GEOGRAPHICLIB_PRECISION == 2 || GEOGRAPHICLIB_PRECISION >= 5 ? 6 : \

Definition Math.hpp:35

The order of the series approximation used in AuxLatitude. GEOGRAPHICLIB_AUXLATITUDE_ORDER can be set to one of [4, 6, 8]. Use order appropriate for double precision, 6, also for GEOGRAPHICLIB_PRECISION == 5 to enable truncation errors to be measured easily.
