def next(bits: Int): (Int, Randomizer)

Get a certain number of random bits.
Get a certain number of random bits.
You don't usually call this directly. Instead, call more-specific functions such as nextInt, which calls this for the correct number of bits and then casts that to the desired type.
bits
The number of random bits you need.
returns
The random bits, and the next Randomizer to user.
def nextBit: (Int, Randomizer)

Get a 1 or a 0.
Get a 1 or a 0.

Get a random 8-bit Byte.
returns
A random Byte, and the next Randomizer to use.
def nextChar: (Char, Randomizer)

Get a random 16-bit Char.
Get a random 16-bit Char.
Note: this intentionally avoids invalid Unicode chars between 0xD800 and 0xDFFF; when one of those is generated, this instead returns a Char between 0x0000 and 0x00FF. So this function slightly favors that first code block. (Which is the most common one in practice, anyway.)
returns
A random Char, and the next Randomizer to use.
def nextDouble: (Double, Randomizer)

Get a random Double.
Get a random Double.
This will randomize the sign, exponent and mantissa, so it can return any possible Double.
returns
A random Double, and the next Randomizer to use.
def nextDoubleBetween0And1: (Double, Randomizer)

Get a random Double between 0 and 1.
Get a random Double between 0 and 1.
When working with Double, you often want a value between 0 and 1 -- this sort of proportion is a common use case for Double. This function makes it easy to grab one.
returns
A random Double in that range, and the next Randomizer to use.
def nextFiniteDouble: (FiniteDouble, Randomizer)

Get a random non-infinite Double.
Get a random non-infinite Double.

returns
A random finite Double, and the next Randomizer to use.
def nextFiniteFloat: (FiniteFloat, Randomizer)

Get a random non-infinite Float.
Get a random non-infinite Float.
This can return either a positive or negative value, or zero, but guards against returning either Float.PositiveInfinity, Float.NegativeInfinity, or Float.NaN.
returns
A random finite Float, and the next Randomizer to use.
def nextFloat: (Float, Randomizer)

Get a random Float.
Get a random Float.
This will randomize the sign, exponent and mantissa, so it can return any possible Float.
returns
A random Float, and the next Randomizer to use.
def nextFloatBetween0And1: (Float, Randomizer)

Get a random Float between 0 and 1.
Get a random Float between 0 and 1.
When working with Floats, you often want a value between 0 and 1 -- this sort of proportion is one of the more common use cases for Floats. This function makes it easy to grab one.
returns
A random Float in that range, and the next Randomizer to use.
def nextInt: (Int, Randomizer)

Get a random 32-bit Int.
Get a random 32-bit Int.
returns
A random Int, and the next Randomizer to use.
def nextList[T](length: PosZInt)(implicit genOfT: Generator[T]): (List[T], Randomizer)

Get a random list of elements of type T.
Get a random list of elements of type T.
This function requires an implicit parameter that says how to generate values of T, as well as the number of them to generate. (Which may be zero.)
T
The type to generate.
length
How many values to generate for the List.
genOfT
A Generator, that provides values of type T.
returns
A List of values of the desired type.

Get a random 64-bit Long.
returns
A random Long, and the next Randomizer to use.
def nextNegDouble: (NegDouble, Randomizer)

Get a random Double less than zero.
Note: it is possible (although rare) for this to return Double.NegativeInfinity. If you want to avoid that, use nextNegFiniteDouble instead.
returns
A random negative Double, and the next Randomizer to use.
def nextNegFiniteDouble: (NegFiniteDouble, Randomizer)

Get a random Double less than zero.
Get a random Double less than zero.
This guards against returning Double.NegativeInfinity, so you can have confidence that the returned number is real and finite.
returns
A random negative Double, and the next Randomizer to use.

Get a random Float less than zero.
Get a random Float less than zero.

returns
A random positive Long (or zero), and the next Randomizer to use.
def nextRandomizer: Randomizer

Computes the next Randomizer to use.
Computes the next Randomizer to use.
Since Randomizer is immutable (and would thus return the same value over and over), you don't usually use the same instance more than once. Instead, you should fetch the next one, and use that for the next operation.
You usually don't need to call this directly; instead, the next Randomizer is returned from each operation, along with the random value.
returns
The next Randomizer, ready to use.
def nextShort: (Short, Randomizer)

Get a random 16-bit Short.
Get a random 16-bit Short.
returns
A random Short, and the next Randomizer to use.
def nextString(length: PosZInt): (String, Randomizer)

Get a random String.
Get a random String.
This takes a desired length, and generates a String of that length. Do not expect this String to make any sense -- it is literally just a string of random Unicode characters, and will typically contain little or no conventional ASCII.
length
The number of characters to include in the String.
returns
A highly-random String of the specified length, and the next Randomizer to use.
