[F. approximation, 280 The largest capacity and the most noble dispositions are but an approximation to the proper standard and true symmetry of human nature. Isa Tayle Not directly, but by succe ive approximations , do mankind reach correct conclusions. H. Spencer , Prin, of Biol., § 147. 2. In math . and phys . : ( a ) A continual approach to a true result; the proce by which the value of a quantity is calculated with continually increasing exactne without ever being actually ascertained. ( b ) A result so obtained; a result which is not rigorously exact, but is so near the truth as to be sufficient for a given purpose.Horner's method of approximation (named for its inventor, W. G. Horner, died 1837), a method of solving numerical equations, the most salient features of which are that each approximate value is obtained from the last by Taylor's theorem, and that the coefficients of the development are calculated by a certain systematic procedure.
