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

Constructors

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.

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

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).

stdUniform :: Distribution StdUniform a => RVar aSource

Get a "standard" uniformly distributed value. 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) => RVar aSource

Like stdUniform but only returns positive values.

integralUniform :: Integral a => a -> a -> RVar aSource

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

realFloatUniform :: RealFloat a => a -> a -> RVar aSource

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

floatUniform :: Float -> Float -> RVar Float Source

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

doubleUniform :: Double -> Double -> RVar Double Source

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

fixedUniform :: HasResolution r => Fixed r -> Fixed r -> RVar (Fixed r)Source

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

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

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) => RVar aSource

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

realFloatStdUniform :: RealFloat a => RVar aSource

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

fixedStdUniform :: HasResolution r => RVar (Fixed r)Source

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

floatStdUniform :: RVar Float Source

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

doubleStdUniform :: RVar 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.
