Quadruple play Quadruple play In telecommunications, quadplay play or quad play is a marketing term combining the triple play service of broadband Internet access, television and telephone with wireless service provisions. This service set is also sometimes humorously referred to as "The Fantastic Four". "Mobile service provisions" refers in part to the ability of subscribers to purchase mobile phone like services, as is often seen in co-marketing efforts between providers of landline services. It also reflects the ambition to gain wireless access on the go to voice, internet, and content/video without tethering to a network via cables. Given advances in LTE and
Quadruple-precision floating-point format the double-double technique above, although that technique does not implement IEEE quadruple precision), since direct hardware support for quadruple precision is, as of 2016, less common (see "Hardware support" below). One can use general arbitrary-precision arithmetic libraries to obtain quadruple (or higher) precision, but specialized quadruple-precision implementations may achieve higher performance. A separate question is the extent to which quadruple-precision types are directly incorporated into computer programming languages. Quadruple precision is specified in Fortran by the codice_2 (module codice_3 from Fortran 2008 must be used, the constant codice_4 is equal to 16 on most processors), or as codice_5, or in
