# Random Range Node
## Description
Returns a pseudo-random number value based on input **Seed** that is between the minimum and maximum values defined by inputs **Min** and **Max** respectively.
Whilst the same value in input **Seed** will always result in the same output value, the output value itself will appear random. Input **Seed** is a **Vector 2** value for the convenience of generating a random number based on a UV input, however for most cases a **Float** input will suffice.
## Ports
| Name | Direction | Type | Description |
|:------------ |:-------------|:-----|:---|
| Seed | Input | Vector 2 | Seed value used for generation |
| Min | Input | Float | Minimum value |
| Max | Input | Float | Maximum value |
| Out | Output | Float | Output value |
## Generated Code Example
The following example code represents one possible outcome of this node.
```
void Unity_RandomRange_float(float2 Seed, float Min, float Max, out float Out)
{
float randomno = frac(sin(dot(Seed, float2(12.9898, 78.233)))*43758.5453);
Out = lerp(Min, Max, randomno);
}
```
