OR Calculator: Online Bitwise OR in Any Number Base
Use the OR Calculator to apply bitwise OR to 2–6 operands, with each value entered in a selectable base. Choose a bit width, then inspect the result in all four bases and in a bit-by-bit visual grid. The calculation is BigInt-based, making it easier to check how set bits from multiple inputs combine.
The OR Calculator is a browser-based tool for calculating bitwise OR, also called bitwise disjunction. Use this online bitwise OR calculator to combine 2–6 operands in a single chained operation. Each value can use a selectable base, so you can work with inputs represented in different bases.
Enter the operands, choose a bit width, and review the result in all four bases. The calculator uses BigInt for its calculation and includes a bit-by-bit visual grid to make the operation easier to inspect. These views help you check both the converted result and how the input bits combine.
Bitwise OR combines corresponding bits: a result bit is set when the corresponding bit is set in at least one operand. Values can be represented in different bases, but the underlying bitwise operation is about their bits. Viewing the result in four bases and in a grid can help when checking a calculation or understanding how multiple values affect it.
The OR Calculator runs entirely in your browser. Your input is processed on your device; it is not uploaded, stored, or sent to a server. Once the page has loaded, the calculator works offline without a server dependency.
This tool is useful for developers and DevOps engineers who need to calculate or verify bitwise OR values, inspect bit-level results, or combine several operands without setting up a separate calculation.
Step 1: Enter 2–6 operand values. The calculator supports chained OR operations, so you can combine more than two inputs.
Step 2: Select a base for each operand. This lets you work with values entered in different bases.
Step 3: Choose a bit width to set the width for the bit-level view.
Step 4: Read the result in all four bases and use the visual grid to inspect the operation bit by bit.
Use case: Work out a bitwise OR value without reaching for a spreadsheet. Enter the operands and review the calculated result in multiple bases.
Use case: Check a figure you were handed instead of trusting it. Compare the displayed result with the inputs and bit-by-bit grid.
Use case: See how the result changes when you edit one of the inputs. This is useful when testing how individual bit values affect a combined result.
Use case: Combine several bit masks or flag values in one calculation. Chaining 2–6 operands makes it easier to check the combined value.
Use case: Verify a result when your operands are written in different bases. Choose a base for each value and inspect the output in all four bases.
Use case: Explore how the chosen bit width relates to a result. The visual grid provides a bit-by-bit way to review the calculation.
