Data.Random.Distribution.Uniform

Synopsis

Documentation

uniform :: Distribution Uniform a => a -> a -> RVar a Source

uniformT :: Distribution Uniform a => a -> a -> RVarT m a Source

data StdUniform t Source

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).

Constructors

StdUniform 

stdUniform :: Distribution StdUniform a => RVar a Source

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 Source

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 Source

Like stdUniform but only returns positive values.

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

Like stdUniform but only returns positive values.

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

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

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

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

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

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

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

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) Source

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 Source

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 Source

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 Source

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

realFloatStdUniform :: RealFloat a => RVarT m a Source

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

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

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

floatStdUniform :: RVarT m Float Source

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

doubleStdUniform :: RVarT m Double Source

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

realStdUniformCDF :: Real a => a -> Double Source

The CDF of the random variable realFloatStdUniform.

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

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