Recommended 10 articles for the PHP floor () function

The numeric function is one of the commonly used functions, but also to learn MySQL must, commonly used are as follows: 1, Ceil: Returns the smallest integer value greater than a number: 2, Floor: And on the contrary, returns the maximum integer value less than a number: 3, round: Returns the value after a value is rounded: for example, The second parameter of the round represents the number of decimal digits that need to be preserved. 4. Truncate: Returns the value after a value has been truncated: unlike round, the second parameter represents the number of decimal digits that need to be retained, regardless of the number of decimal digits that need to be left behind. Note: The above examples are integers, but these functions can also handle negative numbers the same way. The numeric functions are more than these, but these few I personally think are more commonly used, so just record these few.
