Abstract
A computing device has a rounding processor that inputs therein a set of plural (K) input data INthrough INK comprising z bits. The rounding processor selects an ensured bit field depending upon the state of usage of each of specific areas A of upper z/2 bits of the 32-bit input data INthrough INK and rounds the corresponding input data to z/2. As a result of rounding processing, shift information SHIFT of lower (16−n) bits of each discarded non-specific area B is stored in a memory area. D-through D-K of the rounded respective 16 bits are subjected to multiplication by a multiplier. A digit adjuster shifts multiplication results to the left on the basis of the shift information SHIFT respectively stored in the memory areas to adjust digits.
