Interface RandomGenerator

public interface RandomGenerator

Interface for uniform pseudo-random number generators.

Method Summary
`double`	`nextDouble()` Returns a 64 bit uniformly distributed random number in the open unit interval `(0.0,1.0)` (excluding 0.0 and 1.0).
`float`	`nextFloat()` Returns a 32 bit uniformly distributed random number in the open unit interval `(0.0f,1.0f)` (excluding 0.0f and 1.0f).
`int`	`nextInt()` Returns a 32 bit uniformly distributed random number in the closed interval `[Integer.MIN_VALUE,Integer.MAX_VALUE]` (including `Integer.MIN_VALUE` and `Integer.MAX_VALUE`);
`long`	`nextLong()` Returns a 64 bit uniformly distributed random number in the closed interval `[Long.MIN_VALUE,Long.MAX_VALUE]` (including `Long.MIN_VALUE` and `Long.MAX_VALUE`).
`double`	`raw()` Returns a 32 bit uniformly distributed random number in the open unit interval `(0.0,1.0)` (excluding 0.0 and 1.0).

Method Detail

raw

public double raw()

Returns a 32 bit uniformly distributed random number in the open unit interval (0.0,1.0) (excluding 0.0 and 1.0).

nextDouble

public double nextDouble()

Returns a 64 bit uniformly distributed random number in the open unit interval (0.0,1.0) (excluding 0.0 and 1.0).

nextInt

public int nextInt()

Returns a 32 bit uniformly distributed random number in the closed interval [Integer.MIN_VALUE,Integer.MAX_VALUE] (including Integer.MIN_VALUE and Integer.MAX_VALUE);

nextLong

public long nextLong()

Returns a 64 bit uniformly distributed random number in the closed interval [Long.MIN_VALUE,Long.MAX_VALUE] (including Long.MIN_VALUE and Long.MAX_VALUE).

nextFloat

public float nextFloat()

Returns a 32 bit uniformly distributed random number in the open unit interval (0.0f,1.0f) (excluding 0.0f and 1.0f).
