Triple metre Triple metre Triple metre (or Am. triple meter, also known as triple time) is a musical metre characterized by a "primary" division of 3 beats to the bar, usually indicated by 3 (simple) or 9 (compound) in the upper figure of the time signature, with , , and being the most common examples. The upper figure being divisible by three does not of itself indicate triple metre; for example, a time signature of usually indicates compound duple metre, and similarly usually indicates compound quadruple metre. Shown below are a simple and a compound triple drum pattern. It is reasonably common
Quadruple-precision floating-point format switch) or simply as being synonymous with double precision (e.g. Microsoft Visual C++), rather than as quadruple precision. On a few other architectures, some C/C++ compilers implement codice_8 as quadruple precision, e.g. gcc on PowerPC (as double-double) and SPARC, or the Sun Studio compilers on SPARC. Even if codice_8 is not quadruple precision, however, some C/C++ compilers provide a nonstandard quadruple-precision type as an extension. For example, gcc provides a quadruple-precision type called codice_14 for x86, x86-64 and Itanium CPUs, and on PowerPC as IEEE 128-bit floating-point using the -mfloat128-hardware or -mfloat128 options; and some versions of Intel's C/C++ compiler
