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 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
