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 implement nearly quadruple precision using "pairs" of double-precision values is sometimes called double-double arithmetic. Using pairs of IEEE double-precision values with 53-bit significands, double-double arithmetic can represent operations with at least a 2×53=106-bit significand (actually 107 bits except for some of the largest values, due to the limited exponent range), only slightly less precise than the 113-bit significand of IEEE binary128 quadruple precision. The range of a double-double remains essentially the same as the double-precision format because the exponent has still 11 bits, significantly lower than the 15-bit exponent of IEEE quadruple precision (a range of for double-double versus for
