# Price, Bin ID and Sqrt Price

The SDK provides comprehensive utility functions for working with bins and prices through the `BinUtils` class:

```typescript
import { BinUtils } from '@cetusprotocol/dlmm-sdk'

// Convert price to bin ID
const binId = BinUtils.getBinIdFromPrice(
  '1040.07',  // price
  2,          // bin step
  true,       // is base coin A
  6,          // decimals for coin A
  9           // decimals for coin B
)

// Convert bin ID to price
const price = BinUtils.getPriceFromBinId(
  -4787,      // bin ID
  2,          // bin step
  6,          // decimals for coin A
  9           // decimals for coin B
)

// Get Q price from bin ID
const q_price = BinUtils.getQPriceFromId(
  -4400,      // bin ID
  100         // bin step
)

// Get price per lamport from Q price
const price_per_lamport = BinUtils.getPricePerLamportFromQPrice(q_price)

// Get liquidity from amounts
const liquidity = BinUtils.getLiquidity('0', '266666', '18431994054197767090')

// Get amount A from liquidity
const amountA = BinUtils.getAmountAFromLiquidity('4101094304427826916657468', '18461505896777422276')

// Get amount B from liquidity
const amountB = BinUtils.getAmountBFromLiquidity('4919119455159831291232256')


// Split bin liquidity info
const split_bin_infos = BinUtils.splitBinLiquidityInfo(bin_infos, 0, 70)

// Get position count between bin ranges
const positionCount = BinUtils.getPositionCount(-750, 845)

// Find min/max bin ID for a given bin step
const { minBinId, maxBinId } = BinUtils.findMinMaxBinId(10)
```

These utility functions are particularly useful when:

* Setting up price ranges for liquidity positions
* Calculating optimal bin ranges for trading strategies
* Converting between different price representations
* Managing liquidity distributions across bins
* Analyzing position density and distribution

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cetus-1.gitbook.io/cetus-developer-docs/developer/via-sdk-v2/sdk-modules/cetusprotocol-dlmm-sdk/price-bin-id-and-sqrt-price.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
