1. An apparatus to: (a) obtain a first operand value and a second operand value; (b) determine if the second operand value subtracted from the first operand value is greater than a minimum value; (c) determine if the first operand value is greater than a sum value associated with a minimum operand value; and (d) assert an output signal indicative of an absence of an underflow condition associated with a floating-point value based on conditions associated with the operations (b) and (c).
