- **Namespace:** BUILTIN
- **Runtime name (Lua/JS):** `Sqrt`
- **Side:** client (game native)
- **Name status:** official
- **Documentation:** named only
- **Since game build:** 1207

## Signature

```c
float SQRT(float value);
```

## Parameters

- `value` (`float`)

## Returns

`float`

## Usage

### Lua

```lua
local retval = Sqrt(value)

-- always available, by hash
local retval = Citizen.InvokeNative(0x71D93B57D07F9804, value, Citizen.ResultAsFloat())
```

### JavaScript

```js
const retval = Sqrt(value);

// by hash
const retval = Citizen.invokeNative('0x71D93B57D07F9804', value + 0.0000001, Citizen.returnResultAnyway(), Citizen.resultAsFloat());
```

### C#

```csharp
float retval = Function.Call<float>((Hash)0x71D93B57D07F9804, value);
```

- Float parameters: Lua integers (`10`, or whole numbers decoded from NUI/JSON) are sent as ints and read as garbage. Write `10.0` or `value + 0.0`. The generated JS wrappers add `0.0000001` to non-zero floats for the same reason.
