A real data type is a data type used in a computer program to represent an approximation of a real number. Because the real numbers are not countable, computers cannot represent them exactly using a finite amount of information. Most often, a computer will use a rational approximation to a real number.

Famous quotes containing the words real, data and/or type:

    But with some small portion of real genius and a warm imagination, an author surely may be permitted a little to expand his wings and to wander in the aerial fields of fancy, provided ... that he soar not to such dangerous heights, from whence unplumed he may fall to the ground disgraced, if not disabled from ever rising anymore.
    Sarah Fielding (1710–1768)

    To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.
    F. Scott Fitzgerald (1896–1940)

    The perfect detective story cannot be written. The type of mind which can evolve the perfect problem is not the type of mind that can produce the artistic job of writing.
    Raymond Chandler (1888–1959)
