An Irrational Number is one that cannot be expressed as a ratio.

For example, 2/3 3/5 is clearly a rational number, because it's a ratio.
However, root two is irrational.

Other examples of irrational numbers are EQN:\pi,{\quad}e, (which are transcendental numbers)
and the Golden Ratio EQN:\phi (which is an algebraic number).
