Real Data Type - Floating Point Numbers

Floating Point Numbers

A "floating point" type is a compromise between the flexibility of a general rational type and the speed of fixed-point arithmetic. It uses some of the bits in the data type to specify a power of two for the denominator. See floating point and IEEE Floating Point Standard.

Famous quotes containing the words floating, point and/or numbers:

    “The true reformer does not want time, nor money, nor coöperation, nor advice. What is time but the stuff delay is made of? And depend upon it, our virtue will not live on the interest of our money. He expects no income, but outgoes; so soon as we begin to count the cost, the cost begins. And as for advice, the information floating in the atmosphere of society is as evanescent and unserviceable to him as gossamer for clubs of Hercules.”
    —Henry David Thoreau (1817–1862)

    “There is assuredly no more effectual method of clearing up one’s own mind on any subject than by talking it over, so to speak, with men of real power and grasp, who have considered it from a totally different point of view.”
    —Thomas Henry Huxley (1825–95)

    “Think of the earth as a living organism that is being attacked by billions of bacteria whose numbers double every forty years. Either the host dies, or the virus dies, or both die.”
    —Gore Vidal (b. 1925)
