A floating-point unit and a method of identifying exception cases in a floating-point unit. In one embodiment, the floating-point unit includes: (1) a floating-point computation circuit having a normal path and an exception path and operable to execute an operation on an operand and (2) a decision circuit associated with the normal path and the exception path and configured to employ a flush-to-zero mode of the floating-point unit to determine which one of the normal path and the exception path is appropriate for carrying out the operation on the operand.
