Etymology
From, term coined by Scottish mathematician from  and ; compare , from analogous. The word λόγος had an original meaning of a word or a count, as in "recount a tale," or the idea of going over a list. The mathematical sense later expanded to include various specialized senses, including the notion of a ratio, proportion, or inverse proportion.

Noun

 * 1)  For a number $$x$$, the power to which a given base number must be raised in order to obtain $$x$$. Written $$\log_b x$$. For example, $$\log_{10} 1000 = 3$$ because $$10^3 = 1000$$ and $$\log_2 16 = 4$$ because $$2^4 = 16$$.
 * For a currency which uses denominations of 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000, etc., each jump in the base-10 logarithm from one denomination to the next higher is either 0.3010 or 0.3979.
