| digit | 1. <zoology> One of the terminal divisions of a limb appendage; a finger or toe. "The ruminants have the "cloven foot," i. E, two hoofed digits on each foot." (Owen) 2. A finger's breadth, commonly estimated to be three fourths of an inch. 3. <mathematics> One of the ten figures or symbols, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, by which all numbers are expressed; so called because of the use of the fingers in counting and computing. By some authorities the symbol 0 is not included with the digits. 4. <anatomy> One twelfth part of the diameter of the sun or moon; a term used to express the quantity of an eclipse; as, an eclipse of eight digits is one which hides two thirds of the diameter of the disk. Origin: L. Digitus finger; prob. Akin to Gr, of uncertain origin; possibly akin to E. Toe. Cf. Dactyl. Source: Websters Dictionary (01 Mar 1998) |

| binary | Compounded or consisting of two things or parts; characterised by two (things). Binary arithmetic, that in which numbers are expressed according to the binary scale, or in which two figures only, 0 and 1, are used, in lieu of ten; the cipher multiplying everything by two, as in common arithmetic by ten. Thus, 1 is one; 10 is two; 11 is three; 100 is four, etc. <chemistry> Binary compound, the theory that all chemical compounds consist of two constituents of opposite and unlike qualities. Origin: L. Binarius, fr. Bini two by two, two at a time, fr. Root of bis twice; akin to E. Two: cf. F. Binaire. Source: Websters Dictionary (01 Mar 1998) |
