Quadruple jump controversy it is better to attempt a triple Axel, which is safer and more likely to be landed cleanly. Additionally, the difference in base value between a triple Axel and a triple lutz is 2.2 points, whereas between a quadruple toe and a triple Axel it is only 1.6 points. The degree of difficulty, however, between a triple Axel and a quad is greater than the degree of difficulty between a triple Lutz and a triple Axel. Following the figure skating competition in Vancouver, the ISU was urged to reexamine the scoring system at its general assembly scheduled for June, 2010,
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
