I am trying problem 16 from project euler, i want to add a00 integers 50 decimal places each.So i searched and found BigIntegerLibrary, but can't find any good reference material on what are the varoius functions and operators in the library.
Please provide me some decent material on how to use the library......

My guess is the problem wants you to create your own BigInteger program, not use a ready-made library. What do you actually learn by using someone else's code?
