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 Quadruple-precision floating-point format In computing, quadruple precision (or quad precision) is a binary floating-point-based computer number format that occupies 16 bytes (128 bits) in with precision more than twice the 53-bit double precision. This 128-bit quadruple precision is designed not only for applications requiring results in higher than double precision, but also, as a primary function, to allow the computation of double precision results more reliably and accurately by minimising overflow and round-off errors in intermediate calculations and scratch variables. William Kahan, primary architect of the original IEEE-754 floating point standard noted, "For now the 10-byte Extended format is a
