摘要

Rounding apparatus is disclosed which provides consistent rounding of positive and negative numbers in 2's complement representation for floating point operations on binary digital computers. In the disclosed embodiment of the invention, a general purpose computer is described in which apparatus is provided for performing the normal arithmetic and logical operations required for data processing. The computer is augmented by additional apparatus for modifying floating point operands so that consistent results are obtained in processing both positive and negative numbers, primarily during store operations.
