FAQ
What is two's complement?
The usual way computers store negative integers. For example, -1 in 8 bits is stored as 11111111 (0xFF).
Does it handle very large numbers?
Yes. It uses BigInt and works up to 4096 digits without rounding.
Are fractions supported?
No, only integers (positive or negative).
