Java Calculate with crazy large numbers

When I say crazy, I mean like 8192 bits integers and floats.

That's really not that crazy. It's not like that's going to tax the memory in your machine or anything.

Use BigInteger for integers, and BigDecimal for floating point values. I don't believe there's a type for "big binary floating point numbers".

Just as an example of the kind of numbers you're looking at:

import java.math.BigInteger;

class Test {
   public static void main(String[] args) {
       byte[] bytes = new byte[8192/8];
       bytes[0] = 127;
       System.out.println(new BigInteger(bytes));
   }
}

Output:
