To emphasize further Jens-Peer's observation that outputs like
a = HoldForm[ 1 2 1 0 1.0 2 1]
2 0 1. 2
is to do with formatting:
FullForm[HoldForm[ 1 2 1 0 1. 2 1]]
HoldForm[Times[1,2,1,0,1.`,2,1]]
Note that
List@@@a
{1,2,1,0,1.,2,1}
Compare
1.0 x
1. x
with
1 x
x
But it is interesting that presence of 0 does not result in the output being
formatted as 0, inspite of
0 x
0
