97/98 = ≈98.98%
Rounded to 2 decimal places.
A value like 98.98% might show up when nearly all items in a shipment arrive on time, or when a device reports its battery health. It describes a result that is very close to complete, with only a small part missing.
You can picture 97 out of 98 items as a full group with just one item missing. That makes it easy to estimate the value as just under 99%.
A common mix-up is to read 98.98% as exactly 99%. It is close, but it is still slightly lower, so rounding can hide a small difference.
