One of the goals with the algorithms in GeographicLib is to deliver accuracy close to the limits for double precision. In order to develop such algorithms it is very useful to be have accurate test data. For this purpose, I used Maxima's bfloat capability, which support arbitrary precision floating point arithmetic. As of version 1.37, such high-precision test data can be generated directly by GeographicLib by compiling it with GEOGRAPHICLIB_PRECISION equal to 4 or 5.

Here's what you should know:

The following steps needed to be taken
