Documentation by Kevin Jackson and Gavin Sinclair.

When you require ‘rational‘, all interactions between numbers potentially return a rational result. For example: 

  1.quo(2)              # -> 0.5
  require 'rational'
  1.quo(2)              # -> Rational(1,2)

See Rational for full documentation.

Methods

Rational  

Public Instance methods

Rational(a, b = 1)

Creates a Rational number (i.e. a fraction). a and b should be Integers: 

  Rational(1,3)           # -> 1/3

Note: trying to construct a Rational with floating point or real values produces errors: 

  Rational(1.1, 2.3)      # -> NoMethodError
