800/796 = ≈100.5%
Rounded to 2 decimal places.
A value like 800/796 can show up when something is just slightly above its target, such as a store selling 800 items after expecting 796. It represents about 100.5%, so the result is a little more than the full amount planned.
To picture it quickly, imagine a 100% progress bar filled completely, with a tiny extra sliver added on the end. Since the numerator and denominator are very close, you can estimate the fraction as just over 1, or just over 100%.
A common point of confusion is thinking that 100.5% means only half of one percent more than 100 in a noticeable way. It actually means the amount is 0.5 percentage points above 100%, which is a very small increase.
