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
Owned-and-operated television stations in the United States (channel 2) to Fox. CBS then unsuccessfully sought to affiliate with other stations in the market before it eventually purchased low-rated ethnic independent WGPR-TV (channel 62) and changed the station's callsign to WWJ-TV (a callsign once used by one of the stations that CBS approached for an affiliation, WDIV-TV) in 1995. The station continues to receive low ratings, and after a brief attempt at running an 11:00 p.m. newscast from 2001 to 2002 that was produced by sister station WKBD-TV (which voluntarily shut down its news department shortly afterward to enter into a short-lived news share agreement with WXYZ-TV), was
