Im sure you can pass a hex String into the constructor of BigInteger as
well. BigInteger bi = new BigInteger("FFFFFFFFFFFFFFFFFFFFFFFFFFFF",16);

Will the BigInteger Class go to any base ?

Memorized? I wish I had that kind of memory retention

That is the opposite direction.

Java Docs say:

Throws:
NumberFormatException - val is not a valid representation of a
BigInteger in the specified radix, or radix is outside the range from
Character.MIN_RADIX to Character.MAX_RADIX, inclusive.

which at least on my system means 2..36 !

I don't think any programmer has memorized it all ...
