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:

    “They [the children] live in a world of delightful imagination; they pursue persons and objects that never existed; they make an Argosy laden with gold out of a floating butterfly,—and these stupid [grown-up people] try to translate these things into uninteresting facts.”
    —Woodrow Wilson (1856–1924)

    “What I am anxious to do is to secure my legislation.... What I want to do is to get through that, and if I can point to a record of usefulness of that kind, I am entirely willing to quit office.”
    —William Howard Taft (1857–1930)

    “... there are persons who seem to have overcome obstacles and by character and perseverance to have risen to the top. But we have no record of the numbers of able persons who fall by the wayside, persons who, with enough encouragement and opportunity, might make great contributions.”
    —Mary Barnett Gilson (1877–?)
