BigInteger

Remarks

The BigInteger can represent a positive or negative value limited in size by only by memory. Negative values are represented in a Twos Complement fashion mimicking the way the hardware and VB uses signed integer values.

The value is represented internally as an array of Integers. This was selected over Bytes because of the speed increase with working with multiple bytes simultaneously. However, Integers are never revealed outside of the class, only byte arrays.

ShiftRight	Performs a bit shifting operation to the the right.
SquareRoot	Returns the integer square root of a BigInteger.
Subtract	Subtracts a value to this instance of BigInteger.
TestBit	Tests a specific bit in the number to determine if it is set (1) or not (0).
ToArray	Returns a byte array representing the number.
ToString	Returns a human readable string of characters representing the number.
XorBits	Performs a bitwise XOR of this BigInteger instance and the value passed in.
