Abstract
The present invention is a method and apparatus for rounding a result operand of a floating-point (FP) operation which causes an underflow. The FP operation is recomputed using a truncate rounding mode to generate an underflowed operand. The underflowed operand is denormalized and providing characteristic bits. A rounding bit is generated based on the characteristic bits. The rounding bit is merged with the denormalized operand to generate the rounded result operand.
