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 stations were subsequently acquired by the Sinclair Broadcast Group; WLWC, in turn, has since been spun off to OTA Broadcasting, LLC. In June 2010, CBS announced the sale of its Norfolk, Virginia CW O&O WGNT (channel 27) to Local TV, then owner of that market's CBS affiliate WTKR-TV (channel 3) (as well as seven former Fox O&O stations). This created the second television duopoly in that market (the first involved LIN TV-owned NBC affiliate WAVY-TV (channel 10) and Fox affiliate WVBT (channel 43)). As part of the deal, Local TV would take over the operations of WGNT through a time
