Line 6:
The solutions may assume that the base of the number in the string is known. In particular, if your language has a facility to guess the base of a number by looking at a prefix (e.g. "0x" for hexadecimal) or other distinguishing syntax as it parses it, please show that.
The reverse operation is in task [[

Binary conversion is built in to PARI/GP, this script can convert from bases2-36 to bases 2-36. I've had help with this script at http:\\mersenneforums.org . The main flaw in this script I see is that it doesn't allow 36^x-1 type strings, I'll have to add that on later.
