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:

    “Again we mistook a little rocky islet seen through the “drisk,” with some taller bare trunks or stumps on it, for the steamer with its smoke-pipes, but as it had not changed its position after half an hour, we were undeceived. So much do the works of man resemble the works of nature. A moose might mistake a steamer for a floating isle, and not be scared till he heard its puffing or its whistle.”
    —Henry David Thoreau (1817–1862)

    “When women reach the age of maturity, Mother Nature sometimes overworks their frustration to the point of irrationalism. Like the middle-aged man...who finds himself looking longingly at a girl in her early twenties.”
    —Mark Hanna. Nathan Hertz. Dr. Von Loeb (Otto Waldis)

    “All experience teaches that, whenever there is a great national establishment, employing large numbers of officials, the public must be reconciled to support many incompetent men; for such is the favoritism and nepotism always prevailing in the purlieus of these establishments, that some incompetent persons are always admitted, to the exclusion of many of the worthy.”
    —Herman Melville (1819–1891)
