Exponential Notation Calculator

Let's start with what exponential notation is. Exponential notation, or E notation, is one of many names referring to scientific notation.

It is a method to convert very small or very large numbers into a quickly readable format that doesn't keep out too much information about the number.

The only difference between regular scientific notation and exponential notation is the swap of the ×10n×10n factor by EE or, less frequently, ee, both followed by the exponent nn.

Our exponential notation calculator automatically outputs any number you write converted to e notation. Read the following section to learn how to do it by yourself!

To convert a number to exponential notation:

1. Write down the number, e.g., 0.00023453.
2. Move the decimal point to the right of the first non-zero digit.
3. Compare to the original number:
   • If the decimal moved left, the exponent is positive; else
   • The exponent is negative.
4. Count the number of places moved. This is the exponent.
5. Write the first three non-zero digits (round the last) followed by e and the exponent. Example: 2.35e-4.

Give it a try! Follow the steps and then compare the result with our exponential notation calculator.
