Abstract (en)

[origin: WO9110190A1] A method which utilizes a single preprocessing step (214, 216) to modify a divisor (D) in floating point division and to enable an exception correction and error checking operation (104, 108) to run concurrently with a division operation. The invention permits achievement of the correct predetermined result if an exception is present or the quotient if no exception occurs.
