Abstract
An exponent subtractor system (226) for a floating point adder (200) generates an exponent result (EXP.sub.-- low) and a rounded exponent result (EXP.sub.-- high) for an addition operation performed on two floating point numbers and generates overflow (Overflow.sub.-- low, Overflow.sub.-- high) and underflow flags (Underflow.sub.-- low, Underflow.sub.-- high) for the exponent result and the rounded exponent result before the completion of the updating of the exponent result in an exponent subtractor (52, 72).
