# random::float4_01

Generates a pseudo-random 4D vector with single-precision components between 0 and 1.

## Declaration

```swift
float4 random::float4_01()
```

## Return Value

Return Value A pseudo-random 4D single-precision vector with components in the range [0.0, 1.0].

## Discussion

Discussion This function generates a random 4D vector where each component is independently generated in the range [0.0, 1.0] using single-precision floating-point format. The internal random seed is incremented for subsequent calls. note:
