Quadruple jump controversy for the quadruple jump and penalizing skaters if it is not done successfully. In 2008, the scoring system adopted a requirement that a failed quad receive a deduction of up to three points. This has led to some skaters feeling that attempting to do a quad is not worth the risk and reward, as much easier jumps present a better opportunity for athletes to collect the needed points. "I had one fall in my program on a triple lutz. They considered it a double with a fall. I got 1.09 points. Then Nobunari Oda fell on a quad but they
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
