Bitwise OR compares two matching bits. If either bit equals 1, the result for that position becomes 1.
Formula: Result = A | B
| Bit A | Bit B | A OR B |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
The calculator first converts both inputs into the chosen bit width. It then checks every bit pair and builds the final output.
A bitwise OR operation calculator helps you combine two integers at the bit level. It checks each matching bit position and returns 1 when either bit is 1. This makes the tool useful for masks, flags, permissions, packed values, and low level math work.
In maths and computing, bitwise OR is simple but powerful. It preserves every active bit from both values. If one number contains a bit that the other lacks, the result still keeps that active position. Because of this behavior, OR is widely used in binary logic, digital systems, and software development.
This calculator accepts decimal, binary, octal, and hexadecimal inputs. It also aligns values to a selected bit width. That helps you inspect padded binary forms and compare each bit clearly. Seeing the aligned digits reduces mistakes during manual checking.
The formula is direct. For every position, 0 OR 0 becomes 0. The other three combinations become 1. Written compactly, result = A | B. The operator joins set bits from both numbers into one output value.
A calculator like this is useful for students, engineers, analysts, and developers. It can verify homework, explain binary logic, and test mask based rules. It also helps when reading protocol fields, hardware registers, or compact option values stored inside integers.
This page shows decimal, binary, octal, and hexadecimal outputs together. It also explains signed interpretation based on the chosen width. That matters when the leading bit represents sign in two's complement form. A clear width setting makes the final value easier to interpret.
Use this tool when you need fast, accurate, and readable OR results. Enter two numbers, choose the base, select the bit width, and submit. The calculator then displays the merged result, conversions, and a per bit comparison table for deeper understanding.
Bitwise OR is especially helpful when combining feature switches. One value may enable logging, another may enable access, and the final result keeps both states active. This saves storage and speeds checks. Instead of managing many separate variables, you can store several yes or no conditions inside one integer and inspect them later with masks.
That makes binary reasoning easier during exams, debugging sessions, and documentation.
It compares matching bits from two values. A result bit becomes 1 when either input bit is 1. Only 0 OR 0 returns 0.
Yes. Choose the correct input base first. You may also use prefixes such as 0b, 0o, and 0x for convenience.
Bit width controls alignment and signed interpretation. The same digits can represent different signed values when the leading bit changes meaning.
Yes. Negative numbers are shown using two's complement within the selected width. Choose a width large enough to represent the value safely.
Unsigned output treats all bits as magnitude. Signed output uses the leftmost bit as the sign bit within the chosen width.
It is common in masks, permissions, flags, protocol fields, hardware registers, compression logic, and compact configuration storage.
It lists each bit position, its weight, the bit from Number A, the bit from Number B, and the final OR bit.
