## How do you convert E to number?

To convert SN to a decimal number, you start with the number left of the multiplication sign (or “E”) and move the decimal point right (if positive exponent) or left (if negative exponent) the number of places indicated by the power-of-ten exponent.

As you move the decimal point, add zeros for placeholders as needed..
