X86 Extended Precision Format - Need For The 80-bit Format
... A notable example of the need for a minimum of 64 bits of precision in the significand of the extended precision format is the need to avoid precision loss when performing exponentiation on double precision values ... can use in sequence to perform exponentiation using the equation In order to avoid precision loss, the intermediate results "log2 x" and "y log2 x" must be computed with much higher precision because effectively both ... An IEEE 754 double precision value can be represented as where s is the sign of the exponent (either 0 or 1), E is the unbiased exponent which is an integer that ranges from 0 to 1023, and M is the ...

In 2009, the Cray Jaguar performed at 1.75 petaFLOPS, beating the IBM Roadrunner for the number one spot on the TOP500 list ... processor reaches 109 gigaFLOPS (Intel Core i7 980 XE) in double precision calculations ...

Famous quotes containing the words numbers, double and/or precision:

    He bundles every forkful in its place,
    And tags and numbers it for future reference,
    So he can find and easily dislodge it
    In the unloading. Silas does that well.
    He takes it out in bunches like birds’ nests.
    Robert Frost (1874–1963)

    Each in their double Eden closed
    They fail to see the gardener there
    Has planted Error....
    Philip Larkin (1922–1986)

    Some authorities hold that the young ought not to lie at all. That, of course, is putting it rather stronger than necessary; still, while I cannot go quite so far as that, I do maintain, and I believe I am right, that the young ought to be temperate in the use of this great art until practice and experience shall give them that confidence, elegance and precision which alone can make the accomplishment graceful and profitable.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
