Editorial Policy & Accuracy Commitment

At NepaCalc, we believe that mathematical tools must be precise, reliable, and transparent. Our Editorial Policy outlines how we verify formulas, review content, and maintain the highest standards of accuracy for our calculators and educational resources.

1. Formula Verification Process

Every calculator on NepaCalc undergoes a rigorous verification process before publication. We source our formulas exclusively from recognized, authoritative mathematical references, such as:

  • Wolfram MathWorld for advanced geometry and calculus.
  • MIT OpenCourseWare for engineering and applied mathematics.
  • NIST (National Institute of Standards and Technology) for unit conversions and physical constants.
  • ISO/IEC Standards for specialized engineering and financial metrics.

2. The Review Process

All tools and accompanying educational content are thoroughly evaluated by the NepaCalc Mathematics Team. Our review process includes:

  • Mathematical Audits: Checking formulas against edge cases, limits, and undefined domains.
  • Code Verification: Ensuring that the underlying JavaScript or WebGL code precisely executes the mathematical formulas without floating-point errors.
  • Peer Review: Multiple team members review complex tools (like the 3D Graph Calculator) to ensure pedagogical clarity and correctness.

3. Update & Correction Policy

Mathematics doesn't change, but best practices in computation and education do. We regularly audit our tools to improve performance and user experience.

If a user reports an error or if we discover a discrepancy, our team will:

  • Investigate the issue within 48 hours.
  • Deploy a patch immediately if a calculation error is confirmed.
  • Document the change in our Public Changelog.

Our Commitment to You

We are committed to providing free, accessible, and mathematically sound tools for students, educators, and professionals globally. Trust is earned through accuracy, and we strive to earn your trust with every calculation.
