Triple top and triple bottom Triple top and triple bottom Triple top and triple bottom are reversal chart patterns used in the technical analysis of stocks, commodites, currencies, and other assets. Formation The formation of triple tops is rarer than that of double tops in the rising market trend. The volume is usually low during the second rally up and lesser during the formation of the "third top." The peaks may not necessarily be spaced evenly like those which constitute a Double top. The intervening valleys may not bottom out at exactly the same level, i.e. either the first or second may be lower. The
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
