Data.RatioInt

Description

Provides a specialised version of Ratio for Int.

Runs about ten times faster than Ratio while being half as fast as floating-point types.

Synopsis

data RatioInt
(%) :: Int -> Int -> RatioInt

Documentation

data RatioInt #

Rational numbers, with numerator and denominator of the Int type.
