nextUniform()
Generates and returns a new random floating-point value within the characteristics of the distribution.
Declaration
func nextUniform() -> FloatReturn Value
A random floating-point value within the range [delta, 1.0], where delta is the ratio of the lowestValue and highestValue properties.
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.
