Double check also be possible. For example, in the position shown, after Black plays 1...d5, White plays 2.exd6e.p. quintuple check (the "moa" is a non-leaping knight which first takes a diagonal step, then an orthogonal one). After the "en passant" capture, five pieces check the black king: both moas, the rook, the grasshopper and the bishop. In xiangqi, the Chinese version of chess, triple check and even quadruple check is possible even without using fairy pieces, as in the following examples: Double check In chess, a double check is a check delivered by two pieces simultaneously. In chess notation, it is almost
Quadruple-precision floating-point format Quadruple-precision floating-point format In computing, quadruple precision (or quad precision) is a binary floating-point-based computer number format that occupies 16 bytes (128 bits) in with precision more than twice the 53-bit double precision. This 128-bit quadruple precision is designed not only for applications requiring results in higher than double precision, but also, as a primary function, to allow the computation of double precision results more reliably and accurately by minimising overflow and round-off errors in intermediate calculations and scratch variables. William Kahan, primary architect of the original IEEE-754 floating point standard noted, "For now the 10-byte Extended format is a
