I've been searching around for quite a while, and I've found almost nothing on how BigInteger actually holds its numbers. Are they an array of chars? Something else? And how is data converted to/from BigInteger?
From what I've found, I am assuming that all of the Big___ classes hold data as a character array. Is this how it actually works? Or is it just people's guess?
I'm asking because I have been working on my own implementation of something like BigInteger, but I can't figure out how to hold numbers larger than
Long.MAX_VALUE (I don't remember the actual number).
Thanks in advance.
