How it's calculated
x = m × 10ⁿ, where 1 ≤ |m| < 10. e-notation writes 10ⁿ as “en”.
Common questions
What is e-notation?
A shorthand where “e” replaces “× 10^”. So 4.52e-5 means 4.52 × 10⁻⁵ = 0.0000452.
What is engineering notation?
Same idea, but the exponent is always a multiple of 3 to match SI prefixes like kilo, mega, milli, micro.
