  1. noun Mathematics The power to which a base, such as 10, must be raised to produce a given number. If nx = a, the logarithm of a, with n as the base, is x; symbolically, logn a = x. For example, 103 = 1,000; therefore, log10 1,000 = 3. The kinds most often used are the common logarithm (base 10), the natural logarithm (base e), and the binary logarithm (base 2).

  • In the custom of the country the nose of an enemy stands as the logarithm of his head, which is inconvenient of transportation in number; and, though the Prince had forbidden the mutilation of the dead, it was impossible to enforce the prohibition out of Montenegro, and this was the only proof of the actual fruits of victory permitted by the circumstances. —  The Autobiography of a Journalist, Volume II
  • * In [[logarithm]] s, the base is the quantity raised to the power of the logarithm to return the given number. —  Citizendium, the Citizens' Compendium - Recent changes [en]
  • Discrete logarithm - are complete enough for approval. —  Citizendium, the Citizens' Compendium - Recent changes [en]
  • E is the product of five factors, the four leading ones being: pi, rho, L and the square of A; and the product of these four is multiplied by the mathematical function called the natural logarithm (LOGe) of the ratio Ro / Ri. —  CounterPunch
  • Numbers like e (the base of the natural logarithm, which may be defined by means of an infinite sum or infinite product), pi (the circumference of a circle divided by the diameter - which may also be defined in terms of an infinite sum), or phi (the ratio of the golden mean - one half of the sum of one and the square root of five). —  RealClimate
