  2. Octuple-precision floating-point format - Wikipedia

    en.wikipedia.org/wiki/Octuple-precision_floating...

    Apple Inc. had an implementation of addition, subtraction and multiplication of octuple-precision numbers with a 224-bit two's complement significand and a 32-bit exponent. [1] One can use general arbitrary-precision arithmetic libraries to obtain octuple (or higher) precision, but specialized octuple-precision implementations may achieve ...

  3. List of arbitrary-precision arithmetic software - Wikipedia

    Programming languages that support arbitrary precision computations, either built-in, or in the standard library of the language: Ada: the upcoming Ada 202x revision adds the Ada.Numerics.Big_Numbers.Big_Integers and Ada.Numerics.Big_Numbers.Big_Reals packages to the standard library, providing arbitrary precision integers and real numbers.

  4. Data structure alignment - Wikipedia

    en.wikipedia.org/wiki/Data_structure_alignment

    However, when the alignment of offset is already equal to that of align, the second modulo in (align - (offset mod align)) mod align will return zero, therefore the original value is left unchanged. Since the alignment is by definition a power of two, [a] the modulo operation can be reduced to a bitwise AND operation.

  5. Octal - Wikipedia

    en.wikipedia.org/wiki/Octal

    To convert integer decimals to octal, divide the original number by the largest possible power of 8 and divide the remainders by successively smaller powers of 8 until the power is 1. The octal representation is formed by the quotients, written in the order generated by the algorithm. For example, to convert 125 10 to octal: 125 = 8 2 × 1 + 61

  6. Talk : List of XML and HTML character entity references

    en.wikipedia.org/wiki/Talk:List_of_XML_and_HTML...

    I don't think that the standard references octal numbers, but some of my text tools (e.g. Unix's od(1) command) output octal representations of data. It sure would be convenient to search on whatever we've got without having to convert to hex. Since   was the one that triggered this thought, here's a proposal for an alternative.

    Vertical alignment with the surrounding text can also be a problem; a work-around is described in the "Alignment with normal text flow" section below. The CSS selector of the images is img.tex . Apart from function and operator names, as is customary in mathematics, variables and letters are in italics; digits are not.

  8. Quadruple-precision floating-point format - Wikipedia

    en.wikipedia.org/wiki/Quadruple-precision...

    On x86 and x86-64, the most common C/C++ compilers implement long double as either 80-bit extended precision (e.g. the GNU C Compiler gcc [13] and the Intel C++ Compiler with a /Qlong‑double switch [14]) or simply as being synonymous with double precision (e.g. Microsoft Visual C++ [15]), rather than as quadruple precision.

  9. Escape sequences in C - Wikipedia

    en.wikipedia.org/wiki/Escape_sequences_in_C

    For example, \11 is an octal escape sequence denoting a byte with decimal value 9 (11 in octal). However, \1111 is the octal escape sequence \111 followed by the digit 1 . In order to denote the byte with numerical value 1, followed by the digit 1 , one could use "\1""1" , since C concatenates adjacent string literals.
