Description

This module implements common types

Synopsis

type Number = Double type Delta = Number type Text = String type IntegerNumber = Int type RatioNumber = Ratio IntegerNumber toInteger :: Number -> IntegerNumber toRatio :: IntegerNumber -> RatioNumber class Invariant a where invariant :: a -> Bool unzipMaybe :: [Maybe (a, b)] -> ([Maybe a], [Maybe b]) zipMaybe :: ([Maybe a], [Maybe b]) -> [Maybe (a, b)]
