approximate value

The math teacher has been talking about approximate figures these days. For example: 6.38 insurance is 6 and insurance is 6.4. The teacher also talked about some ways for you to learn how to find the divisor: keep the integer to one tenth, the percentile to one percent, the thousandth to one half, the millionth to one third, and use the "rounding" method.

The divisor and "rounding" can be used in real life, but some can't. For example, there was a spring outing in the class, and the teacher told everyone, "Come to school at 7: 50 tomorrow morning! Please don't be late! " "Isn't 7: 50 rounded to 8: 00?" Xiao Ming thought. The next morning, Xiao Ming arrived at school at eight o'clock, but he didn't even see anyone. Confused Xiao Ming used rounding method and was ten minutes late, which is the consequence of being smart. You should use your own brain in the future, but you can't use it indiscriminately and mechanically, otherwise you will suffer a big loss like Xiao Ming.
