Abstract
A computer and a method of using the computer to separate a floating-point number into high and low parts and for evaluating a dominant arithmetic object and a remainder object. The dominant object is associated with the first arithmetic object by using the high parts of the floating-point number. The evaluation of a remainder arithmetic object associates the first arithmetic object with the high and low parts of the floating-point numbers. A sum of the dominant and remainder arithmetic objects returns a value corresponding to the first arithmetic object.
