About this tool
Write a number in scientific, E and engineering notation, with optional significant figures.
The exponent is ⌊log₁₀|x|⌋ and the coefficient is x ÷ 10^exponent, between 1 and 10. Engineering notation uses exponents that are multiples of 3.
Formula: x = a × 10ⁿ, 1 ≤ |a| < 10
Example: Number = 0.0001, Significant figures (0 = keep all) = 0 → Scientific notation = 5.2 × 10^-5, E notation = 0.0001.
Precision is limited to about 15 significant digits.
