= Radix Rational

  require 'radix'

== Initialization

Radix::Rational's initializer takes a numerator and a denominator,
either of which can be an Integer, Float, String or Array along witha
an integer base.

Give a integer value, it will automatically be converted to the base
specified.

  check do |num, dem, base, eqf|
    r = Radix::Rational.new(num, dem, base)
    r.assert == eqf
  end

  ok  1, 1,  2,  1.0

  ok  8, 1, 10,  8.0
  ok  8, 5, 10,  1.6
  ok  8, 8, 10,  1.0

  ok 10, 1, 10, 10.0
  ok 10, 2, 10,  5.0
  ok 10, 5, 10,  2.0

  ok  8, 1, 16,  8.0
  ok 16, 1, 16, 16.0

== Reduction

  check do |a, x|
    r = a.reduce
    r.assert == x
  end

== Operations

=== Addition

  check do |a, b, x|
    r = a + b
    r.assert == x
  end

  ok [8,5].br(10), [1,2].br(10), [21,10].br(10)

  ok [8,5].br(10), 1, [13,5].br(10)

  ok [8,5].br(10), 0.5, [21,10].br(10)

=== Subtraction

  check do |a, b, x|
    r = a - b
    r.assert == x
  end

  ok [8,5].br(10), [1,2].br(10), [11,10].br(10)

=== Multiplication

  check do |a, b, x|
    r = a * b
    r.assert == x
  end

  ok [8,5].br(10), [1,2].br(10), [8,10].br(10)

=== Division

  check do |a, b, x|
    r = a / b
    r.assert == x
  end

  ok [8,5].br(10), [1,2].br(10), [16,5].br(10)
