I think there are a few conventions for expressing sig digits. Where I was taught… 2600 has 2 sd 2600. Has 4 sd 2.6e3 has 2sd 2.60e3 has 3 sd Edit. If I had been in charge of setting sd rules, I would’ve said … 2600 has 4 sd 260? Has 3 sd 26?? Has 2 sd The fact zeros are overloaded (they can be placeholders or they can actually mean 0) is confusing to students. |
