How to Use This Calculator
  1. Enter any number (including very large or very small values such as 0.000045 or 6,022,000,000,000,000,000,000).
  2. Set the number of Significant Figures to control how many digits appear in the mantissa.
  3. Scientific notation format: coefficient × 10^exponent (e.g., 1.235 × 10⁵ for 123,500).
  4. Engineering notation groups the exponent in multiples of 3, aligning with SI prefixes (kilo, mega, giga, etc.).
  5. Standard form output writes the number without exponent notation for easy reading when it fits.
  6. The calculator handles positive and negative numbers; zero displays as 0 × 10⁰.
