# Numbers

You can enter whole and decimal numbers as you would expect. Separators can be included in large numbers like the comma in `10,000`

to make numbers easier to read. By default, these thousands separators will be inserted automatically as you type a number.

```
42 + 12
2.5 - .7
23,000 + 500
```

```
54
1.8
23,500
```

NOTE

To change what character to use as a thousands separator, go to`System Preferences > Language & Region`

and click the `Advanced`

buttonNOTE

To change whether separators should be automatically inserted as you type a number, go to`Preferences > Editing > Automation`

## Shortened Notation

Large and small numbers can be tedious to type, so Figures includes a few ways to make this easier. You can use common names for these numbers like `million`

or `billion`

, called *cardinal names*. You can also use a metric symbol after the number as a shortcut. For example, `5k`

is the same as `5,000`

.

```
20 million × 3
500 tenths + 1 tenth
5k + 5 hundred
2M meters
5T + 200G
5 mega
5M
```

```
60 million
50.1
5,500
2 million m
5.2 trillion
5
5 million
```

NOTE

These examples and the table below use**short**cardinal names (most common). Figures also supports

**long**cardinal names if you prefer. Go to

`Preferences > Format > Region`

to change which scale to use.Here are the cardinal names and prefixes supported by Figures:

Cardinal name | Metric prefix | Symbol | Value |
---|---|---|---|

septillion | yotta | Y | 10²⁴ |

sextillion | zetta | Z | 10²¹ |

quintillion | exa | E | 10¹⁸ |

quadrillion | peta | P | 10¹⁵ |

trillion | tera | T | 10¹² |

billion | giga | G | 10⁹ |

million | mega | M | 10⁶ |

thousand | kilo | k | 10³ |

hundred | — | — | 10² |

tenth | — | — | 10⁻¹ |

hundredth | — | — | 10⁻² |

thousandth | — | — | 10⁻³ |

millionth | micro | μ | 10⁻⁶ |

billionth | nano | n | 10⁻⁹ |

trillionth | pico | p | 10⁻¹² |

quadrillionth | femto | f | 10⁻¹⁵ |

quintillionth | atto | a | 10⁻¹⁸ |

sextillionth | zepto | z | 10⁻²¹ |

septillionth | yocto | y | 10⁻²⁴ |

NOTE

Some metric symbols near zero aren't supported because they're uncommon and have conflicts. For example, the symbol for`thousandth`

is `m`

which could be confused with the symbol for `meters`

.NOTE

Metric prefix names like`kilo`

and `micro`

are used with units to change their scale (e.g. `kilometers`

or `microliters`

). They're included here to show what the symbols stand for, but they can't be used with numbers by themselves. Use the symbol instead. See Units for more on using metric prefixes.
