Double Precision

Some articles on double, precision, double precision:

Long Double - long Double in C - Implementations
... architecture, most compilers implement long double as the 80-bit extended precision type supported by that hardware (sometimes stored as 12 or 16 bytes to maintain data structure alignment) ... An exception is Microsoft Visual C++ for x86, which makes long double a synonym for double ... on Microsoft Windows supports extended precision, but requires the /Qlong‑double switch for long double to correspond to the hardware's extended precision format ...
Apollo Guidance Computer - Design - Instruction Set
... in such a way as to propagate a carry for multi-precision add/subtract ... it is a normal possibility (as in multi-precision add/subtract), the TS is followed by CAF ZERO (CAF = XCH to fixed memory) to complete the formation of the carry (+1, 0, or -1) into the next higher-precision word ... Angles were kept in single precision, distances and velocities in double precision, and elapsed time in triple precision ...
FLOPS - Records
109 gigaFLOPS (Intel Core i7 980 XE) in double precision calculations ... GPU computing processors perform around 515 gigaFLOPS in double precision calculations, and the AMD FireStream 9270 peaks at 240 gigaFLOPS ... In single precision performance, Nvidia Tesla C2050 computing processors perform around 1.03 teraFLOPS and the AMD FireStream 9270 cards peak at 1.2 teraFLOPS ...
Computational Photography (artistic) - File Formats For Computational Photography - PDM and PLM
... Most computational photography uses double precision arrays, e.g. 64 bits per pixel (64BPP), Portable Double Maps use the headers P7 (greyscale) and P8 (color) in place of P5 (Portable Grey Map) and P6 (Portable Pix Map), respectively ... Portable Lightspace Maps also use double precision data, but quantimetrically, usually either linear or logarithmic ...

Famous quotes containing the words precision and/or double:

    Women on trains
    have a life
    that is exactly livable
    the precision of days flashing past
    Audre Lorde (1934–1992)

    Society’s double behavioral standard for women and for men is, in fact, a more effective deterrent than economic discrimination because it is more insidious, less tangible. Economic disadvantages involve ascertainable amounts, but the very nature of societal value judgments makes them harder to define, their effects harder to relate.
    Anne Tucker (b. 1945)
