Double or nothing 40 dollars (20x2). If Player A wins the initial bet will be canceled. Player B either wins double or Player A wins nothing. In poker, a double or nothing tournament is a sit'n'go tournament where half of the surviving players get double the buy-in and the eliminated half does not receive any prizes. Double or nothing tournaments are mostly played by ten players (five players win) or six players (three win), although multi-table versions, such as for 20 players, exist. The rake in these tournaments is usually smaller than in standard sit'n'go tournaments. Some poker rooms also offer triple or
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
