ABSTRACT:
In a floating-point arithmetic operation system performing an arithmetic operation on two given operands X, Y and providing the result Z of the arithmetic operation, the operands X and Y are each classified according to their attributes; and, at least part of the bits of the operand X, at least part of the bits of the operand Y or a predetermined set of bits are adopted as at least part of the result Z of the operation when the results of the classifications are one of predetermined combinations.
