BigInteger
Arbitrary-precision integers for values that exceed SmallInteger range.
BigInteger is created automatically when SmallInteger arithmetic overflows the 48-bit range. You never need to create BigIntegers explicitly — they appear transparently from operations like factorial on large numbers, exponentiation, or simply adding beyond SmallInteger limits.
BigInteger supports all the same arithmetic (+, -, *, /, \\, //), comparison (<, >, <=, >=, =), and bitwise (bitAnd:, bitOr:, bitXor:, bitShift:) operators as SmallInteger. Mixed BigInteger/SmallInteger operations are handled automatically — the SmallInt operand is promoted. Mixed BigInteger/Float operations produce Float results.
If a BigInteger result fits back in the SmallInteger range, it is automatically demoted for efficiency.

Return true if the receiver is greater than or equal to the argument.
Return the remainder.
Return the bitwise AND.
Return the bitwise OR.
Shift left by count bits (negative shifts right).
