# Tick Math

* **Name**: `evoswap::tick_math`
* **Description**: This module provides functions to work with ticks and their corresponding square root prices. In EVO, the square root price is represented in a fixed-point format 48x80, using a `u128` number.

#### Sqrt Price Formula <a href="#sqrt-price-formula" id="sqrt-price-formula"></a>

To compute the client-side square root price (`sqrt_price_x80`), use the following formula:

`sqrt_price_x80 = floor(sqrt(price) * 2^80)`

For example, if the price is 1.5, then:

`sqrt_price_x80 = floor(sqrt(1.5) * 2^80) = 1480625697465890259337216`
