War of the Quadruple Alliance the Triple Alliance, which became the Quadruple Alliance for which the war is named. Meanwhile, in July 1718 the Spanish, this time with 30,000 men again led by the Marquess of Lede, had also invaded Sicily, which had been awarded to the Duke of Savoy. They took Palermo on 7 July and then divided their army in two. De Lede followed the coast to besiege Messina between 18 July and 30 September, while the Duke of Montemar conquered the rest of the island. The French, Austrians, and British now demanded Spanish withdrawal from Sicily and Sardinia. The attitude of Victor
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
