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.

this number |

0.1 | 1d (deci) | 10^-1 | 1e-1 | |

0.01 | 1c (centi) | 10^-2 | 1e-2 | 1% (percent) |

0.000001 | 1m (milli) | 10^-3 | 1e-3 | |

0.00000001 | 1u (micro) | 10^-6 | 1e-6 | |

0.0000000001 | 1n (nano) | 10^-9 | 1e-9 | |

0.000000000001 | 1p (pico) | 10^-12 | 1e-12 | |

1,000 | 1k (kilo) | 10^3 | 1e3 | |

1,000,000 | 1M (mega) | 10^6 | 1e6 | |

1,000,000,000 | 1G (giga) | 10^9 | 1e9 | |

1,000,000,000,000 | 1T (tera) | 10^12 | 1e12 |

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`

.
