DESCRIPTION

• Defines class-instances for Ratio.
• CAVEAT: rational numbers are converted imprecisely to floating-point for representation as XML. To remedy the loss of precision on reading from XML, they're rounded to the epsilon for IEEE double-precision https://en.wikipedia.org/wiki/Machine_epsilon.

Orphan instances

Integral i => XmlPickler (Ratio i)

Methods

xpickle :: PU (Ratio i)

(Integral r, Random r) => Random (Ratio r)

Methods

randomR :: RandomGen g => (Ratio r, Ratio r) -> g -> (Ratio r, g)

random :: RandomGen g => g -> (Ratio r, g)

randomRs :: RandomGen g => (Ratio r, Ratio r) -> g -> [Ratio r]

randoms :: RandomGen g => g -> [Ratio r]
