Is this the sort of thing you need?
11.3^i.5. NB. plain output with default precision
1 11.3 127.69 1442.9 16304.7
10j2": 11.3^i.5. NB. Vector with 2dp
1.00 11.30 127.69 1442.90 16304.74
10j2": ,.11.3^i.5. NB. Column vector with 2dp
1.00
11.30
127.69
1442.90
16304.74
(This looks poor on my iPad, but should be fine with a fixed width display)
I think there is/are add-on version/s of printf that I’m not familiar with.

PS I think Ric has just posted something too...
