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 implement nearly quadruple precision using "pairs" of double-precision values is sometimes called double-double arithmetic. Using pairs of IEEE double-precision values with 53-bit significands, double-double arithmetic can represent operations with at least a 2×53=106-bit significand (actually 107 bits except for some of the largest values, due to the limited exponent range), only slightly less precise than the 113-bit significand of IEEE binary128 quadruple precision. The range of a double-double remains essentially the same as the double-precision format because the exponent has still 11 bits, significantly lower than the 15-bit exponent of IEEE quadruple precision (a range of for double-double versus for
