A decimal is rational if
  • it terminates (stops) (like -0.763); or
  • it does not terminate but it has a set of infinitely repeating digits (like 4.8134134134...)
A decimal is irrational if it does not terminate and it does not have repeating digits (like pi or the number "e" or many square roots)
