Quadruple jump controversy maneuver in figure skating. "When it comes to a quadruple jump- it is quite simple really. If no one except for the one Russian skater is able to perform it, you need to make believe that this jump does not exist at all." TV commentators and experts saw Plushenko's "saving power" in managing to land a seemingly off-axis triple Axel as a testament to what real mastery is all about, as few would have been able to save it. "This is exactly what determines the great skill of a figure skater – the ability to save a jump when needed,
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
