Floating point computation unit having means for rounding the floating point computation result

摘要

A floating point computation unit for use in a data processing system in which the mantissa processing means provides an overall computation result a portion of which represents the desired mantissa result. A carry- in bit is added to the least significant bit of the overall result and is propagated through the mantissa processing means so that it can be added to the least significant bit of the desired mantissa result to provide a rounding of such desired result.
