10 recommended articles about numerical functions

Numerical function is one of the commonly used functions, and it is also a must for learning mysql. The commonly used ones are as follows: 1. ceil: returns the smallest integer value greater than a certain number: 2. floor: opposite to the previous one, returns less than a certain number The maximum integer value of the number: 3. Round: Returns the rounded value of a certain value: As shown above, the second parameter of round represents the number of decimal places that need to be retained. 4. Truncate: Returns the truncated value of a certain value: The difference here from round is that regardless of the decimal place that needs to be retained, it will be discarded directly. The same second parameter represents the decimal place that needs to be retained. Note: The above examples are all integers, but these functions can also handle negative numbers in the same way. There are more than these numerical functions, but I personally think these are more commonly used, so only these are recorded.
