RE: HP49-50G : —>g gravity calculation = g(latitude, height) with WGS84
Please note for the value calculation of k and e² (e squared):

Most Internet sites and official papers or books show inaccurate "ending" digits, as they use too few digits for a truncate value of the axe b (Pole radius).


For instance they might give
b = 6 356 752.341
or b=6 356 752.3
or b=6 356 752.3412
or b=6 356 752.34125 asf,

instead of more digits, something like
b=6356752.31424517949756...

in order to be able to precess to a more appropriate calculation of k and e² (e squared) after roundings.

Regards,
Gil
