Frequently Asked Questions
What is scientific notation?
Scientific notation writes numbers as a × 10ⁿ where 1 ≤ |a| < 10 and n is an integer. E.g. 0.000056 = 5.6 × 10⁻⁵. It is used to handle very large or very small numbers in science and engineering.
What is E-notation?
E-notation is the computer representation of scientific notation: 5.6e-5 means 5.6 × 10⁻⁵. Most calculators and programming languages use this format.
