1.9995≈2.00

Analysis:

Keep two decimal places, that is, accurate to one hundredth, and only look at the numbers on one thousandth:

If the number on one thousandth is ≥5, then "1" goes to percentile;

If the number on the thousandth bit is less than 5, the number on the thousandth bit and its subsequent numbers will be discarded.

One thousandth of 1.9995 is 9,9 > 5, and the percentile is "1".

1.99+0.0 1=2.00

So, 1.9995≈2.00
