Work through the task
Evaluate integer arithmetic and bitwise operators with signed 64-bit bounds.
- Enter only supported integer literals, parentheses and operators.
- Read the signed decimal result alongside its 64-bit hexadecimal and binary representations. Division truncates toward zero.
- Review the result before copying or downloading. Editing an input invalidates the previous result; keep an original if the transformation matters.
Example to check
(-7 / 3) ^ (1 << 4) → -18; hexadecimal is the 64-bit two’s-complement pattern.
Limits and output behavior
Maximum 4,096 expression characters, 1,000 tokens and 40 nesting levels. Overflow, division by zero, shifts outside 0–63 and code-like syntax are rejected.
Troubleshooting
Check signed 64-bit range, literal syntax, parentheses and shifts 0–63. Division by zero/overflow and unsupported code-like syntax are rejected; integer division truncates toward zero.
Questions
Why does a negative result have a long hexadecimal form?
The hexadecimal/binary views display the 64-bit two’s-complement bit pattern. The signed decimal value can therefore be negative while the bit pattern has high set bits.
