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
Double (basketball) seasons. A quadruple-double is the accumulation of a double-digit number total in four of the five categories in a game. This has occurred four times in the NBA. A quintuple-double is the accumulation of a double-digit number total in all five categories in a game. Two quintuple-doubles have been recorded at the high school level, by Tamika Catchings and Aimee Oertner, but none have occurred in a college or professional game. A similar accomplishment is the five-by-five, which is the accumulation of at least five points, five rebounds, five assists, five steals, and five blocks in a game. In the
