Sample input:

Dec2HexNoLeading0s ( 35243 )

Sample output:

89AB

Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Let (

  // get the hex digit for the least significant nibble (4 bits)
   thisNibble = Middle ( "0123456789ABCDEF" ; Mod (theNumber ; 16) + 1 ; 1 ) ;

  // see if theNumber passed is bigger than a nibble, if so recurse to process the more significant nibbles
  If ( theNumber < 16 ;
    "" ;  // blank means we're not adding any extra
    Dec2HexNoLeading0s ( Int ( theNumber / 16 ) ) // add the more significant nibbles
  ) &
  thisNibble // always return the least significant nibble

)

This function can stand alone, it returns as many digits as required to express the # in hex. My other function, Dec2Hex, specifies how many leading zeros (more useful to see RGB colors in web format.

What are the function parameters for this script? When I paste the script into the "Custom Function Window" it says to specify function paramenters.
