# Large Numbers

Many of the **resources** and stats can quickly reach large numbers, most notably **Bacteria count** and **planet population**.

By default, all numbers bigger than 999 are displayed using the **alphabetic notation**. It is also possible to enable **scientific notation** in the Settings menu, which will change how the numbers are displayed in game.

# Notations

There are two notations (or ways) large numbers can be displayed: **alphabetic** and **scientific**.

## Alphabetic

The alphabetic notation is the default style for displaying numbers in Bacterial Takeover (e.g. 10.500 K, 8.910 Bil, 35.200 bn). It is a non-standard notation that combines common abbreviations (for numbers smaller than 1E+54) with some arbitrary abbreviations (for larger numbers).

The list of abbreviations used by alphabetic notation is provided further below.

## Scientific

Scientific notation is a way of writing numbers that cannot be conveniently displayed using the standard system.

Bacterial Takeover employs a type of scientific notation that is called the **E-notation**. The E stands for exponent and shows how many zeroes a particular number has. This makes it easy to make various calculations. Scientific notation is only used if it has been turned on in the Settings menu or if the number in question is larger than 1E+2079.

The list of abbreviations used by scientific notation is provided further below.

Qadc | Quattuordecillion | 45 | 1E+45 |

Qidc | Quinquadecillion | 48 | 1E+48 |

## Numbers from 1E+54

According to the alphabetic notation, numbers in the range from 1E+54 to 1E+2079 are shown as a combination of two letters ranging from "aa" (1E+54) to "zz".

**Example:**

- 1E+54 = 1 aa
- 1E+57 = 1 ab
- 1E+60 = 1 ac
- 1E+63 = 1 ad

- 1E+132 = 1 ba
- 1E+135 = 1 bb

- 1E+2073 = 1 zx
- 1E+2076 = 1 zy
- 1E+2079 = 1 zz
