There are three situations that are considered approximate:
One is completely within the range of the other party, such as the other party's temperature 15-30 degrees, and you are 20-25 degrees.
The other is crossing, for example, the other person's temperature is 15-30 degrees, while yours is 10-20 degrees. In both cases, you will be rejected.
In the three cases, the formula is almost the same, but the proportion is slightly different, and the functions of different components can be replaced (or can be simply inferred), so it will be regarded as approximate and rejected.
