How We Calculate Results
This calculator tests for divisibility by every whole number from 2 up to the square root of your number — if none divide evenly, the number is prime. Testing only up to the square root is a well-known optimization, since any larger factor would have a corresponding smaller one already checked.
The result is based on the inputs you provide and the assumptions described below. Learn more about how WIN Calculator develops and reviews its calculations.
Example
For example, try a round number first (like 10 or 100) to confirm the calculator matches what you'd expect by hand, then switch to your real numbers.
Assumptions
- Inputs are treated as exact real numbers — the calculator doesn't infer units or significant figures beyond what you actually enter.
- Standard mathematical conventions are used for order of operations, sign, and domain — for example, only real-number results are returned, not complex numbers.
Limitations
- Results are rounded for display — very large, very small, or repeating-decimal results may be truncated; use the formula above directly if you need full precision.
- Inputs outside a formula's valid domain (like a negative number under an even root, or a triangle that can't geometrically exist) produce an error or an undefined result rather than a guessed answer.
Sources
- Standard mathematical definitions and formulas as taught in secondary and college-level mathematics.
Validation
- Every formula in our calculator library is covered by an automated regression test suite that checks its output against known reference values before any code change ships.
- Formulas are written from publicly documented sources — standards bodies, government agencies, or established textbooks — rather than derived from scratch, and are reviewed again whenever the underlying guidance changes.
