  2. Double-precision floating-point format - Wikipedia

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

    Double-precision floating-point format (sometimes called FP64 or float64) is a floating-point number format, usually occupying 64 bits in computer memory; it represents a wide range of numeric values by using a floating radix point. Double precision may be chosen when the range or precision of single precision would be insufficient.

  3. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    size_t is an unsigned integer type used to represent the size of any object (including arrays) in the particular implementation. The operator sizeof yields a value of the type size_t. The maximum size of size_t is provided via SIZE_MAX, a macro constant which is defined in the <stdint.h> header (cstdint header in C++).

    36 bits – size of word on Univac 1100-series computers and Digital Equipment Corporation's PDP-10 56 bits (7 bytes) – cipher strength of the DES encryption standard 2 6: 64 bits (8 bytes) – size of an integer capable of holding 18,446,744,073,709,551,616 different values – size of an IEEE 754 double-precision floating point number

  5. Bed size - Wikipedia

    en.wikipedia.org/wiki/Bed_size

    Single-size beds are usually intended for one person. Double-size beds are usually intended for two persons. Standard bed sizes are based on standard mattress sizes, which vary from country to country. Bed sizes also vary according to the size and degree of ornamentation of the bed frame. Dimensions and names vary considerably around the world ...

    en.wikipedia.org/wiki/Long_double

    The long double type was present in the original 1989 C standard, [1] but support was improved by the 1999 revision of the C standard, or C99, which extended the standard library to include functions operating on long double such as sinl() and strtold().

  7. Word (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Word_(computer_architecture)

    A similar phenomenon has developed in Intel's x86 assembly language – because of the support for various sizes (and backward compatibility) in the instruction set, some instruction mnemonics carry "d" or "q" identifiers denoting "double-", "quad-" or "double-quad-", which are in terms of the architecture's original 16-bit word size.

  9. 8 mm film - Wikipedia

    en.wikipedia.org/wiki/8_mm_film

    Because of the two passes of the film, the format was sometimes called Double 8. The frame size of regular 8 mm is 4.8 mm × 3.5 mm, and 1 meter of film contains 264 pictures. Normally, Double 8 is filmed at 16 or 18 frames per second. Common length film spools allowed filming of about 3 to 4 + 1 ⁄ 2 minutes at 12, 15, 16, and 18 frames per ...
