metric [′me·trik]

(mathematics)

A real valued “distance” function on a topological spaceXsatisfying four rules: forx, y,andzinX,the distance fromxto itself is zero; the distance fromxtoyis positive ifxandyare different; the distance fromxtoyis the same as the distance fromytox; and the distance fromxtoyis less than or equal to the distance fromxtozplus the distance fromztoy(triangle inequality).
