Quadruple-precision floating-point format special characteristics: In addition to the double-double arithmetic, it is also possible to generate triple-double or quad-double arithmetic if higher precision is required without any higher precision floating-point library. They are represented as a sum of three (or four) double-precision values respectively. They can represent operations with at least 159/161 and 212/215 bits respectively. A similar technique can be used to produce a double-quad arithmetic, which is represented as a sum of two quadruple-precision values. They can represent operations with at least 226 (or 227) bits. Quadruple precision is often implemented in software by a variety of techniques (such as
Stations of the Resurrection any Church authorities sought to impose a definitive list, and as a result some churches have commissioned sets of sculptures for the Stations according to their own distinctive scheme which may not be followed elsewhere. (This is similar to the history of the Stations of the Cross, which attained their normative form only after many centuries of widely varying local practice.) As to the "number" of Stations, however, there is general agreement that in order to emphasise the complementarity between the Stations of the Cross and the Stations of the Resurrection there should be fourteen Stations of the Resurrection, as
