   Voici la source :

   /* Function from Guido Socher, guido at linuxfocus dot org, Copyright: GPL */
   function from10toradix(value,radix){
   var retval = ‘’;
   var ConvArray = new initArray(0,1,2,3,4,5,6,7,8,9,’A',’B',’C',’D',’E',’F');
   var intnum;
   var tmpnum;
   var i = 0;

   intnum = parseInt(value,10);
   if (isNaN(intnum)){
   retval = ‘NaN’;
   }else{
   while (intnum > 0.9){
   i++;
   tmpnum = intnum;
   // cancatinate return string with new digit:
   retval = ConvArray[tmpnum % radix] + retval;
   intnum = Math.floor(tmpnum / radix);
   if (i > 100){
   // break infinite loops
   retval = ‘NaN’;
   break;
   }
   }
   }
   return retval;
   }

   function e(id)

   }

   /* Function from Ioswebdesign Copyright: GPL */
   function comp(from)

   switch(from)
   {
