data Uniform t

A definition of a uniform distribution over the type t. See also uniform.

Constructors

Uniform !t !t

A uniform distribution defined by a lower and upper range bound. For Integral and Enum types, the range is inclusive. For Fractional types the range includes the lower bound but not the upper.

data StdUniform t

A name for the "standard" uniform distribution over the type t, if one exists. See also stdUniform.

For Integral and Enum types that are also Bounded, this is the uniform distribution over the full range of the type. For un-Bounded Integral types this is not defined. For Fractional types this is a random variable in the range [0,1) (that is, 0 to 1 including 0 but not including 1).

HasResolution r => Distribution StdUniform (Fixed r)

stdUniform :: Distribution StdUniform a => RVar a

Get a "standard" uniformly distributed variable. For integral types, this means uniformly distributed over the full range of the type (there is no support for Integer). For fractional types, this means uniformly distributed on the interval [0,1).

stdUniformT :: Distribution StdUniform a => RVarT m a

Get a "standard" uniformly distributed process. For integral types, this means uniformly distributed over the full range of the type (there is no support for Integer). For fractional types, this means uniformly distributed on the interval [0,1).

stdUniformPos :: (Distribution StdUniform a, Num a, Eq a) => RVar a

Like stdUniform but only returns positive values.

stdUniformPosT :: (Distribution StdUniform a, Num a, Eq a) => RVarT m a

Like stdUniform but only returns positive values.

integralUniform :: Integral a => a -> a -> RVarT m a

Compute a random Integral value between the 2 values provided (inclusive).

realFloatUniform :: RealFloat a => a -> a -> RVarT m a

realFloatUniform a b computes a uniform random value in the range [a,b) for any RealFloat type

floatUniform :: Float -> Float -> RVarT m Float

floatUniform a b computes a uniform random Float value in the range [a,b)

doubleUniform :: Double -> Double -> RVarT m Double

doubleUniform a b computes a uniform random Double value in the range [a,b)

fixedUniform :: HasResolution r => Fixed r -> Fixed r -> RVarT m (Fixed r)

fixedUniform a b computes a uniform random Fixed value in the range [a,b), with any desired precision.

enumUniform :: Enum a => a -> a -> RVarT m a

realFloatUniform a b computes a uniform random value in the range [a,b) for any Enum type

boundedStdUniform :: (Distribution Uniform a, Bounded a) => RVar a

Compute a random value for a Bounded type, between minBound and maxBound (inclusive for Integral or Enum types, in [minBound, maxBound) for Fractional types.)

boundedEnumStdUniform :: (Enum a, Bounded a) => RVarT m a

Compute a random value for a Bounded Enum type, between minBound and maxBound (inclusive)

realFloatStdUniform :: RealFloat a => RVarT m a

Compute a uniform random value in the range [0,1) for any RealFloat type

fixedStdUniform :: HasResolution r => RVarT m (Fixed r)

Compute a uniform random Fixed value in the range [0,1), with any desired precision.

floatStdUniform :: RVarT m Float

Compute a uniform random Float value in the range [0,1)

doubleStdUniform :: RVarT m Double

Compute a uniform random Double value in the range [0,1)

boundedStdUniformCDF :: (CDF Uniform a, Bounded a) => a -> Double

realStdUniformCDF :: Real a => a -> Double

The CDF of the random variable realFloatStdUniform.

realUniformCDF :: RealFrac a => a -> a -> a -> Double

realUniformCDF a b is the CDF of the random variable realFloatUniform a b.
