The next function converts a binary value to a decimal number. Works +/- 5 times faster than Base2Dec : <lsl>integer binToDec(string val) {

   integer dec = 0;
   integer i = ~llStringLength(val);
   while(++i)
       dec = (dec << 1) + (integer)llGetSubString(val, i, i);
   return dec;

}</lsl>

This one converts a decimal to a binary value:

<lsl>string decToBin(integer val) {

   string binary = (string)(val & 1);
   for(val = ((val >> 1) & 0x7FFFffff); val; val = (val >> 1))
   {
       if (val & 1)
           binary = "1" + binary;
       else
           binary = "0" + binary;
   }
   return binary;

}</lsl>
