Description
A positive power of two has exactly one set bit in its binary integer representation.
A positive power of two has exactly one set bit in its binary integer representation.1
This checker supports the full nonnegative JavaScript safe-integer range instead of truncating values to 32 bits.
When to use Power of Two Checker
Use this tool to apply the stated power of two checker operation with an explicit input and unit basis.
How to use Power of Two Checker and how it works
- Establish the text or game convention described above.
- Enter actualNonnegativeSafeInteger and run the tool.
- Read result.isPowerOfTwo using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualNonnegativeSafeInteger | Nonnegative integer no greater than Number.MAX_SAFE_INTEGER (2^53−1). | number | required; finite; further conditions in the algorithm |
Require a nonnegative safe integer, convert it exactly to BigInt and count set bits by repeatedly clearing the lowest set bit. Return true only when the count is one; zero returns false.
isPowerOfTwo = popcount(n) === 1 Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.isPowerOfTwo | True when the integer has exactly one set bit; zero is false. | boolean |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A returned boolean, signed difference or tied result follows the stated convention; an input error instead means the required input contract was not satisfied. Very large inputs or outputs may be rejected by shared resource limits.
