The logarithms (of sines) tabulated by Napier himself were not logarithms in this restricted sense, but were functions of what are now called Napierian (also Neperian), hyperbolic, or natural logarithms, the base of which, denoted by the symbol ε or e, is 2·71828 +. This system is still in use for analytical investigations, but for common purposes the system used is that invented by Napier's friend Henry Briggs (died 1630), the base of which is 10; the Briggsian or Briggian logarithms are also known as common logarithms (see common adj. and adv. Compounds 2) or decimal logarithms.
