You can enter metric affixes or scientific notation to indicate very large or very small numbers. For scientific notation, you can type either a caret (^) or the letter `e`

followed by a number to indicate an exponent. You can use both positive and negative exponents.

For example, to indicate `0.012`

, you can enter either of the following expressions:

- 1.2*10^-2
- 1.2e-2

To indicate -440,000, you can enter either of the following expressions:

- -4.4*10^5
- -4.4e5

The following table shows how to enter numbers with metric affixes, with scientific notation, and with `e`

notation.

Note: When you use metric affixes or `e`

notation, make sure you do not include spaces between the number and the metric affix or the `e`

.
