The results of comparing floats to doubles in SIO output files are in!
Normalizing to the size of the compressed ASCII file, compressed SIO files
(100 tt events):
Large Small
doubles 1.32 0.98
floats 0.88 0.84
So in the float heavy large detector, doubles really do cost. 32% larger
than compressed ASCII and 50% larger than compressed SIO(float). Is it
worth it? Opinions sought.
Tony.
