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 television stations were on the UHF band, along with the fact it saw the advantage of having a statewide network to share California news coverage and events with, using the resources of KFSN, KGO-TV and KABC-TV. By the time the Fox network launched in October 1986, many of the nation's VHF stations were already affiliated with one of the "Big Three" networks. As a result, Fox had little choice but to affiliate with UHF stations in most markets upon its launch (the few VHF outlets that the network initially affiliated with, a few of which were owned by Fox itself,
