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:

    “I myself have seen the floating ships
    And nothing will ever be the same
    The shouts,
    The harrowing voices within the house.
    I stand apart with an army:
    My mind is graven with ships.”
    —Hilda Doolittle (1886–1961)

    “The ellipse is as aimless as that,
    Stretching invisibly into the future so as to reappear
    In our present. Its flexing is its account,
    Return to the point of no return.”
    —John Ashbery (b. 1927)

    “I had but three chairs in my house; one for solitude, two for friendship; three for society. When visitors came in larger and unexpected numbers there was but the third chair for them all, but they generally economized the room by standing up.”
    —Henry David Thoreau (1817–1862)
