Double (basketball) A triple-double is defined as a performance in which a player accumulates a double digit number total in three of five statistical categories—points, rebounds, assists, steals, and blocked shots—in a game. The most common way for a player to achieve a triple-double is with points, rebounds, and assists, though on occasion players may record 10 or more steals or blocked shots in a game. The origin of the term "triple-double" is unclear. Some sources claim that it was coined by former Los Angeles Lakers public relations director Bruce Jolesch in the 1980s in order to showcase Magic Johnson's versatility, while
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
