# Calculated Field, Leading Zeroes and limiting precision

Greetings

Further to the discussion here:, I have made a few modifications to the calculation provided by jbante. These modifications include:

• Getting the Cardinal directions (N,S,E,W) reporting corrctly for positive (N, E) cardinals and (S, W) for negative cardinals,
• Leading Zeroes on whole degrees for both Latitude and Longitude -to more closely comply with "correct" (perhaps more commonly used and familiar?) notation, and
• Limited the decimal precision of Minutes of arc to 5 places.

So far, so good.

My final stumbling block with this is to get Leading Zeroes in the whole minutes notation of the coordinates. For example, the Decimal Latitude coordinate -4.00699999183416 is correctly rounding to -4.00699999. After calculation, the result is displaying as: S04° .42'... which should be, with "correct" notation: S04° 00.42'. I've tried adding a Right function, without success... I suspect it may be to do with where I am calling that function, but I can't make it work!

The calculation as it currently exists:

Let ( [

~original = LATITUDE ;

~negative = ~original < 0 ; // True (1) if value is negative

~positive = Abs ( ~original ) ;

~degrees = Div ( ~positive ; 1 ) ;

~minutes = Mod ( ~positive ; 1 ) * 60 ;

~decimal = ~degrees + ~minutes / 60 ;

~decimal = If ( ~negative ; 0 - ~decimal ; /* Else */ ~decimal )

] ;

If ( ~negative ; "S" ; "N")

& Right ( "00" & ~degrees ; 2 ) & "° "

& Round ( ~minutes ; 5 ) & "'"

)

Would appreciate any assistance available!
