Developers typically represent numbers as either integers or floats. But occasionally, neither of these is a good choice. What if we want to represent a number as an exact fraction like 2/3 instead of an approximation like 0.667? In that case, our best choice is neither an integer, nor a float, but a "rational." Here's how rationals work in Ruby: You can create rational numbers in many ways 3/2r 1.5.to_r "3/2".to_r Rational(3, 2) Rational math produces rational results 2/3r + 1/3r => (1/1) 2/3r * 1/3r => (2/9) 2/3r / 1/3r => (2/1) Happy coding  |
