Frequently Asked Questions
What is scientific notation?v
Scientific notation writes a number as a coefficient from 1 to less than 10 multiplied by a power of 10.
What is E notation?v
E notation is a compact computer-friendly version, such as 1.23e6 for 1.23 x 10^6.
Can I convert back to standard form?v
Yes. Choose the standard form tab and enter a coefficient and exponent.
Does it support negative exponents?v
Yes. Negative exponents represent small decimal numbers.
