A minor trigonometric bug is also mentioned, but this should should better be ignored for ever. Does not appear to be true on a real 67: 0, [g][4] (=ASIN) => 0.00 [h][0] (=LastX) => 0.00 1, [g][4] (=ASIN) => 90.00 [h][0] (=LastX) => 1.00 1, [g][5] (=ACOS) => 180.00 [h][0] (=LASTX) => 1.00 Perhaps the addendum note only applies to some limited range of s/n?
