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 1954 to 1960). The network wanted to see if a UHF station could effectively compete against VHF stations, and attempted to make the stations more competitive by investing in significant equipment upgrades. However, WBUF consistently ranked behind its VHF competitors, WGR-TV (channel 2, now WGRZ) and WBEN-TV (channel 4, now WIVB-TV). Similarly, WNBC consistently rated behind VHF competitor WNHC-TV (channel 8, now WTNH); WNBC faced an additional problem as its signal was not strong enough to cover New Haven and western Connecticut (nearly all of Connecticut is part of the Hartford-New Haven market). By the time the FCC allocated additional
