What bases are supported?

You can enter operands in binary (base 2), octal (base 8), decimal (base 10), or hexadecimal (base 16). Each operand has its own base selector, so you can mix bases freely.

How does division work?

Division uses integer (floor) division — the fractional part is discarded. The remainder is shown separately below the main result. For example, 10 / 3 gives quotient 3 remainder 1.

How is NOT (bitwise complement) calculated?

NOT uses 32-bit two's complement, which matches the behavior of most programming languages for 32-bit integers. The result is shown as a signed 32-bit value and then formatted in all four bases using that signed interpretation.

What does the binary output look like?

Binary output is grouped into 4-bit nibbles separated by spaces for readability — for example, 1111 0011 instead of 11110011. Leading zeros are added to complete the last group.

Are negative numbers supported?

Negative decimal results are displayed as signed decimal. Binary, octal, and hex representations use two's complement internally for bitwise operations. For display, if the result is negative it is shown with a minus sign in decimal while the other bases show the 32-bit unsigned two's complement pattern.

Summary

Add, subtract, multiply, divide, or apply bitwise operations to binary/hex/octal/decimal numbers.

How it works

Enter Operand A and select its base (BIN, OCT, DEC, or HEX).
Choose an operation from the dropdown: +, -, x, /, AND, OR, XOR, <<, >>, or NOT.
For binary and NOT operations, Operand B is ignored automatically.
Enter Operand B and select its base (also BIN, OCT, DEC, or HEX).
Click Calculate to see the result displayed in binary, octal, decimal, and hexadecimal.

Use cases

Debug bitwise flag logic in embedded systems or low-level programming.
Convert numbers between binary, octal, decimal, and hexadecimal at once.
Verify AND/OR/XOR masks when working with network subnets or permissions.
Check the result of left/right shift operations used in performance-optimized code.
