"Alternatives" on page 219 explains the three definitions of underflow given by the IEEE standards. Note that, though implementations differ as when they raise the underflow flag, a computed value does not differ between implementations. A portable program does not depend on whether the computation of tiny, inexact values raises underflow or not.
