What is the real-time temperature rounding of China weather network for?

Mainly in order to reduce the workload, the calculated data can be transmitted more timely to form relatively accurate real-time weather data. Another is that the current computer temperature measurement drawing is carried out by computer, and there is a certain deviation between computer drawing and manual drawing, especially in terms of curves. I have studied the real-time temperature map of the weather, which is drawn by hand. Ten years ago, now it's all computer maps. After comparison, I found that the current map curve is very smooth, and many times it can not accurately show some changes in the real temperature. Another is that integer calculation saves time and effort, which can reduce a lot of work costs. Everything we are doing now is cost-conscious, and civil weather forecasting is like this. Aviation and military are completely different, and the military is very subtle. It is normal not to find it difficult to understand. I hope my answer is helpful to you.
