But OTOH, if 1.0+2.0 gives 2.999999, that is, not good enough, so there
 is a lower limit here.
1.0 has a fraction of 0
2.0 has a fraction of 0
1.0+2.0 has a fraction with a single HOB set.
all 3 above examples have the hidden bit set.
Any implementation purporting to be IEEE 754 better not give anything
other than 3.0 !!
Bad example. Even IBM and CRAY arithmetics, with all their problems,
were
not that bad.
