Math. [ANTI- 2. Cf. Fr. anti-logarithme.]
† 1. ‘The complement of the logarithm of a sine, tangent, or secant; or the difference between that and the logarithm of ninety degrees.’ Chambers, Cycl. Supp., 1753. Obs.
1796. Hutton, Math. Dict., I. 121.
2. The number to which the logarithm belongs.
1675. Collins, in Rigaud, Corr. Sci. Men, I. 215. Between … 1630 and 1640, Dr. Pell and one Mr. Warner … agreed to make a table of antilogarithms.
1834. Penny Cycl., II. 105. Antilogarithm, as used in this country, means the number to the logarithm. Thus in Briggs’ system, 100 is the antilogarithm of 2, because 2 is the logarithm of 100.
