Quadruple jump controversy important. It's good for me to keep challenging myself. I can't hold back on anything, and taking chances is what sports are about." Plushenko's program was more ambitious and risky with the quadruple toe/ triple toe loop, while Lysacek did not even attempt the quad as a single jump "at the biggest moment on skating's biggest stage." Sports journalist Kevin Blackistone wrote: "What has unfolded at the Vancouver Winter Games in figure skating would be the equivalent of not crediting Shaun White for his double McTwist in the half pipe and rewarding less ambitious snowboarders for getting the basics perfect."
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
