Bitwise Calculator & Bit Inspector
Inspect exact 8–64-bit logic, shifts, signed values and interactive binary words.
What Is the Bitwise Calculator & Bit Inspector?
An exact BigInt-based binary workbench for 8, 16, 32 and 64-bit words. Perform AND, OR, XOR, NOT and three types of shift, then inspect signed decimal, unsigned decimal and hexadecimal values. Individual bits can be toggled directly.
How It Works
Enter operands in decimal or with 0x, 0b or 0o prefixes. Choose a word size and operation. Shifts accept counts from zero through word size minus one. Click a bit in A or B to change it; results update immediately. Copy or download a report.
When to Use It
Explore masks, flags, binary formats and two’s-complement arithmetic. Results wrap to the selected width, unlike unlimited-precision integer arithmetic.
Frequently Asked Questions
- Does It Support 64-Bit Precision?
- Yes. Operations use BigInt, not floating-point Number, so all 64-bit integer values remain exact.
- What Is Arithmetic Right Shift?
- It treats A as a signed two’s-complement word and extends the sign bit. Logical right shift fills the left side with zeros.
