Description

Defines uncertainty types and functions.

Synopsis

data Uncertainty
class HasUncertainty c where
- unc :: Lens' c Uncertainty
uncert :: Lens' Uncertainty (Maybe Double)
prec :: Lens' Uncertainty (Maybe Int)
uncty :: Double -> Maybe Int -> Uncertainty
exact :: Uncertainty
defaultUncrt :: Uncertainty
uncVal :: HasUncertainty x => x -> Double
uncPrec :: HasUncertainty x => x -> Maybe Int

Type

data Uncertainty Source #

Something that may contain an uncertainty value and a precision value.

Class

class HasUncertainty c where Source #

HasUncertainty is just a chunk with some uncertainty associated to it. This uncertainty is represented as a decimal value between 0 and 1 (percentage).

Methods

unc :: Lens' c Uncertainty Source #

Provides the Lens to an Uncertainty.

Instances

Instances details

HasUncertainty UncertQ Source #	Finds the uncertainty of an `UncertQ`.
Instance details Defined in Language.Drasil.Chunk.UncertainQuantity Methods unc :: Lens' UncertQ Uncertainty Source #
HasUncertainty UncertainChunk Source #	Finds the uncertainty of an `UncertainChunk`.
Instance details Defined in Language.Drasil.Chunk.UncertainQuantity Methods unc :: Lens' UncertainChunk Uncertainty Source #

Lenses

uncert :: Lens' Uncertainty (Maybe Double) Source #

prec :: Lens' Uncertainty (Maybe Int) Source #

Constructors

uncty :: Double -> Maybe Int -> Uncertainty Source #

Smart constructor for values with uncertainty.

exact :: Uncertainty Source #

Smart constructor for exact values (no uncertainty).

Constructor

defaultUncrt :: Uncertainty Source #

The default uncertainty is set to 0.1.

Accessors

uncVal :: HasUncertainty x => x -> Double Source #

Accessor for uncertainty value from something that has an uncertainty.

uncPrec :: HasUncertainty x => x -> Maybe Int Source #

Accessor for precision value from something that has an uncertainty.
