Method and apparatus for rounding operands using previous rounding history

摘要

A rounding mechanism and methodology, particularly useful for complex calculations involving multiple numeric operations (e.g., transcendentals) in which rounding performed on source operands, prior to their use in a current numeric operation, is used to determine the manner in which the result of the current numeric operation is rounded. Therefore, the result is rounded based on the rounding history of its source operands.
