ABSTRACT:
In a floating-point multiplier device for two numbers, each represented by an exponent and a mantissa which includes a binary one integer bit, first and second round-up CPA's (carry propagate adders) (41, 42) are supplied with selected bits of mantissa carries and sums to be operable when a mantissa product is not less than one and is less than two and when the product is not less than two, respectively. As a combination of an ultimate exponent and a rounded-off mantissa of a product of the two numbers, a selector (49) selects one of a first combination of an exponent sum and the mantissa product subjected to round down and to no bit shift, a second combination of the exponent sum and the mantissa product subjected to round down and to a one-bit rightward shift, a third combination of a sum exponent and a first rounded mantissa produced by the first round-up CPA, and a fourth combination of the sum exponent plus one and a second rounded mantissa produced by the second round-up CPA.
