rational

Rational numbers (a.k.a fractions) for Carp.

Fractions are expressed as pairs of integers. Mathematical operations and
conversion primitives to and from integers and floating point numbers are
provided.

Installation

(load "git@github.com:carpentry-org/rational@0.4")

Usage

(load "git@github.com:carpentry-org/rational@0.3")
(Rational.new 22 12) ; => (Rational 11/6)
(Rational.mul (Rational.new 22 12) (Rational.new 1 6)) ; => (Rational 2/1)
(Rational.to-int (Rational.new 2 1)) ; => 2
(Rational.to-float (Rational.new 1 4)) ; => 0.25

Please note that conversion can be lossy, because conversion to integer throws
away any non-real value and conversion to floating point values is only as
accurate as floating point numbers are.

Have fun!
