# nextUniform()

Generates and returns a new random floating-point value within the characteristics of the distribution.

## Declaration

```swift
func nextUniform() -> Float
```

## Return Value

Return Value A random floating-point value within the range [delta, 1.0], where delta is the ratio of the lowestValue and highestValue properties.

## Discussion

Discussion When using the GKRandomDistribution class directly, generated numbers are uniform within the range of the distribution. For example, in a distribution whose lowest value is 1 and highest is 20 (as produced by the d20() class method), delta is 1/20 = 0.05; that is, the distribution returns numbers in 5% increments. Subclasses of GKRandomDistribution can alter this quantization, as well as relative probability of generating any particular number within the distribution’s range.
