This VI has a problem with the zone calculation, at least for my location (Longitude 147E, zone 55).

I got a better result using: RoundDown((Longitude + 180.0)/6.0)+1

Also this VI leaves out a final scaling. If a negative Northing is calculated, it should output (Northing+ 10,000,000.0)

(as per referenced javascript implementation).
