### The Basics
|
|
|
|
A denomination is a proper description of a currency amount. It is
|
|
oftentimes a sub-unit of the currency. For example, traditionally a cent is
|
|
1/100th of a particular unit of currency.).
|
|
|
|
Monero denomination names add SI prefixes after dropping the initial "mo"
|
|
for ease of use. Actually, the smallest unit of Monero is 1 piconero
|
|
(0.000000000001 XMR).

### In-depth Information
|
|
|
|
Support for input using SI prefixes was [added to the Monero
|
|
codebase](https://github.com/monero-project/monero/pull/1826) on March 3,
|
|
2017 by [Moneromooo](https://github.com/moneromooo-monero). The smallest
|
|
unit of Monero (10^-12 XMR) was originally called a tacoshi in honor of user
|
|
[Tacotime](https://bitcointalk.org/index.php?action=profile;u=19270), an
|
|
early Monero contributor and was later renamed for ease of use and
|
|
consistancy.
|
|
|
|
### Monerod Implementation
|
|
|
|
The smallest fraction of Monero in the current monerod implementation is
|
|
also known as the @atomic-unit, which is currently one piconero.
