Quadruple jump controversy Quadruple jump controversy At the 2010 Winter Olympics held in Vancouver, British Columbia, Canada, the final results of the men's figure skating competition sparked what has been dubbed a quadruple jump controversy. At the heart of it lies a quadruple jump, the toughest jump there is in figure skating, done in combination with a triple toe loop, which Evgeni Plushenko of Russia landed in both his short and long programs. Evan Lysacek of the United States, however, did not include quads in either of his programs. Plushenko, who led Lysacek by half a point after the short figure skating program,
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
