Scientific Notation Converter

Scientific Notation Converter

Convert numbers between standard form, scientific notation, E-notation, and engineering notation.

Capabilities

• Flexible input: Accepts plain numbers (123456789), E-notation (1.23e8), or "x 10^" format.
• Three output formats: Scientific notation (1.23 × 10⁸), E-notation (1.23e+08), and engineering notation (123.4 × 10⁶).
• Arithmetic: Add, subtract, multiply, and divide numbers in any notation.
• Precision: Uses Python Decimal for accurate handling of very large and very small numbers.

Gotchas

• Engineering notation: Exponent is always a multiple of 3 (matches SI prefixes like kilo, mega, giga).
• Very large numbers: Standard form display may be truncated for numbers with many digits.
• Floating point limits: Extremely large exponents (>308) may exceed float range — the tool uses Decimal internally but the JSON output is a float.
