/*
	Class: BigInteger
	An arbitrarily-large integer.

	<BigInteger> objects should be considered immutable. None of the "built-in"
	methods modify *this* or their arguments. All properties should be
	considered private.

	All the methods of <BigInteger> instances can be called "statically". The
	static versions are convenient if you don't already have a <BigInteger>
	object.

	As an example, these calls are equivalent.

	> BigInteger(4).multiply(5); // returns BigInteger(20);
	> BigInteger.multiply(4, 5); // returns BigInteger(20);

	> var a = 42;
	> var a = BigInteger.toJSValue("0b101010"); // Not completely useless...

/*
	Constructor: BigInteger()
	Convert a value to a <BigInteger>.

	Although <BigInteger()> is the constructor for <BigInteger> objects, it is
	best not to call it as a constructor. If *n* is a <BigInteger> object, it is
	simply returned as-is. Otherwise, <BigInteger()> is equivalent to <parse>
	without a radix argument.

	> var n0 = BigInteger();      // Same as <BigInteger.ZERO>
	> var n1 = BigInteger("123"); // Create a new <BigInteger> with value 123
	> var n2 = BigInteger(123);   // Create a new <BigInteger> with value 123
	> var n3 = BigInteger(n2);    // Return n2, unchanged

	The constructor form only takes an array and a sign. *n* must be an
	array of numbers in little-endian order, where each digit is between 0
	and BigInteger.base.  The second parameter sets the sign: -1 for
	negative, +1 for positive, or 0 for zero. The array is *not copied and
	may be modified*. If the array contains only zeros, the sign parameter
	is ignored and is forced to zero.

	> new BigInteger([5], -1): create a new BigInteger with value -5

	Parameters:

		n - Value to convert to a <BigInteger>.

	Returns:

		A <BigInteger> value.

	See Also:

		<parse>, <BigInteger>

	- "0x" or "0X": *base* = 16

	If any characters fall outside the range defined by the radix, an exception
