Is E The Same As X10?

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..

to multiply by 1010The notation E10 means to multiply by 1010. When working on a calculator, it is common for the calculator to represent very large or very small…

What is a high E value?

The Expect value (E) is a parameter that describes the number of hits one can “expect” to see by chance when searching a database of a particular size. … These high E values make sense because shorter sequences have a higher probability of occurring in the database purely by chance.
