## 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**.

## 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);
|
||
|
|
}
|
||
|
|
```
