How to convert from decimal to hex?

[FoolMuun]

I'm stumped. How does one go about converting decimal values to hex values using JSLT?
E.g. Hex(1234)="4D2"

Here's a possible solution:

def hex(dec)
  if ($dec==0) 0
  else hexcalc($dec,"")

def hexcalc(dec, result)
  let hexdict = ["0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F"]
  if ($dec!=0) hexcalc(floor($dec/16), $hexdict[mod($dec,16)] + $result)  
  else $result

hex(1234)

Output:
"4D2"

Not safe for negative values though, but that can be fixed.

Great to see that you managed to sort this out yourself, and thank you for posting the solution so other people can use it. I think if this question shows up again we'll seriously consider adding the function to the language.
