Arbitrary-precision arithmetic Explanation

Question

I\'m trying to learn C and have come across the inability to work with REALLY big numbers (i.e., 100 digits, 1000 digits, etc.). I am aware that there exist libraries to do

Answer 1

One of the ultimate references (IMHO) is Knuth's TAOCP Volume II. It explains lots of algorithms for representing numbers and arithmetic operations on these representations.

@Book{Knuth:taocp:2,
   author    = {Knuth, Donald E.},
   title     = {The Art of Computer Programming},
   volume    = {2: Seminumerical Algorithms, second edition},
   year      = {1981},
   publisher = {\Range{Addison}{Wesley}},
   isbn      = {0-201-03822-6},
}
