Is the Inverse Flattening definitive for this ellipsoid?
Function IsIvfDefinitive() As Boolean
Missing <returns> documentation for M:Geotools.CoordinateReferenceSystems.IEllipsoid.IsIvfDefinitive
Some ellipsoids use the IVF as the defining value, and calculate the polar radius whenever asked. Other ellipsoids use the polar radius to calculate the IVF whenever asked. This distinction can be important to avoid floating-point rounding errors.
