Double (volleyball) to record one, most likely when a match exceeds three sets, particularly five-set matches. Triple double is defined as an individual performance in which a player accumulates a double digit number total during one match in three of five statistical categories, aces, kills, blocks, digs, and assists. The most common way for a player to achieve a triple-double is with kills, blocks, and digs, usually attained by hitters (i.e., middle blockers, outside hitters, or opposite hitters) who are skilled defensively. Occasionally, setters record a triple-double, typically combining assists, digs, and either kills or blocks. A triple-double is a rare event,
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
