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 on the weaker channel 6 signal under the same calls). "Note: Some stations were owned by Ion Media Networks under its former name Paxson Communications prior to the 1998 launch of Ion Television as Pax TV." Notes:<br> TBN has never sold one of its full-power television stations (either one it owns outright or through its Community Educational Television subsidiary), though several translator stations have been sold off since the digital transition to other parties for either spectrum speculation, to become translators of other commercial stations, or in the case of W41BN in Dothan, Alabama, to become an affiliate of one
