Roots of a·z³ + b·z² + c·z + d.
LATITUDE and AZIMUTH in radians. DISTANCE in meters.
Parse float STRING into an exact rational. XXX it is really simple and the form should be "{-}[0-9]+" or "{-}[0-9]*.[0-9]+"
WGS84 equatorial Earth radius in meter.
WGS84 ellipsoid flattening.
Factors for A-3.
Polynomial factors for C-3.
Cubic root that handles negative numbers.
Returns m12 and M12.
Normalize angle between 0 and π.
lat1 <= 0 and lat1 <= lat2 <= -lat1 (i.e. lat2 is closest to zero).
