I'm sorry, but I am going to respectfully disagree. Full IEEE
comformance is very expensive on the Alpha's and the reason you need it
very uncommon. Martin provoked it by passing a denormal to libg2c, but
*in normal programming* running into denormal should point to some error
in the logic of your algorithms.
[ Unless you're in cosmology and try to express everything in 32-bit
REALs using SI units - my point is that nobody *does* that. ]
