Ratio

Standard functions on rational numbers

Rational numbers, with numerator and denominator of some Integral type. Note that Ratio's instances inherit the deficiencies from the type parameter's. For example, Ratio Natural's Num instance has similar problems to Natural's.

Compose multiple actions to create a ratio. Useful for graphing percentage information, e. g.

connectionUtilizationRate :: IO (Gauge IO)
connectionUtilizationRate = gauge $ ratio openConnectionCount $ return connectionPoolSize

Arbitrary-precision rational numbers, represented as a ratio of two Integer values. A rational number may be constructed using the % operator.
