The statement that the property fee is rounded to one decimal place.

Rounding: an accurate counting method, which rounds the digits after the decimal point. Here "four" means less than five, and "five" is the rounded mantissa. If you look at the previous figures every five days, you will get odd and even numbers. For example, 1.25 keeps one decimal place, because 2 is an even number, so it is 1.2. Another example is 1.35, because 3 is an odd number, it is 1.4.

Mathematically, when encountering multiple decimal places, for the convenience of calculation, several digits will be truncated, and the remaining first digits will be discarded if they are less than four digits, and if they are more than five digits, one will be added to the last digit. For example, 3. 13 19, taking two digits is 3. 13, and taking three digits is 3. 132.
