# Reciprocal Node
## Description
Returns the result of dividing 1 by the input **In**. This can be calculated by a fast approximation on Shader Model 5 by setting **Method** to **Fast**.
## Ports
| Name | Direction | Type | Description |
|:------------ |:-------------|:-----|:---|
| In | Input | Dynamic Vector | Input value |
| Out | Output | Dynamic Vector | Output value |
## Controls
| Name | Type | Options | Description |
|:------------ |:-------------|:-----|:---|
| Method | Dropdown | Default, Fast | Selects the method used |
## Generated Code Example
The following example code represents one possible outcome of this node per **Method** mode.
**Default**
```
void Unity_Reciprocal_float4(float4 In, out float4 Out)
{
Out = 1.0/In;
}
```
**Fast** (Requires Shader Model 5)
```
void Unity_Reciprocal_Fast_float4(float4 In, out float4 Out)
{
Out = rcp(In);
}
```
