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
The Communist Party USA and African Americans did not establish any lasting relations with the Black Panther Party, which was largely destroyed by the early 1970s, and did not recruit any significant number of members from those organizations or win them to its politics. The party maintained some standing in the black community through its former allies, including Coleman Young of Detroit and Gus Newport in Berkeley, California, who were elected to office in the 1970s.
