Quadruple jump controversy the early days of the Olympic Winter Games, skaters performed single jumps. By the middle of the 20th century, they had graduated to double jumps. By the 1980s, the triple Lutz was the benchmark for men. Throughout the '80s, it was the triple Axel, though attempts at a quad were already being made. Finally, a quadruple jump became an essential element in the programs of many men in the '90s and into the new millennium. The fact that fewer skaters than ever before attempt to land the toughest element in figure skating, opting to go for points instead, does not
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
