Mysql numeric processing functions floor and round bitsCN.com
The mysql numeric processing functions floor and round are in mysql. when processing a numeric value, a numeric processing function is used. for example, if there is a float value of 2.13, you only need an integer of 2, the following functions are required: floor and round.
This article mainly introduces the PHP code example for adding a floor number to a message in WordPress. here, it is only for the main comment, not for the comment in the stacked middle floor, if you need a friend, you can refer to the blog comment page that was suddenly found to have a problem recently.

1)fix (N) rounding in the 0 direction , which is a class of functions applied to integer values, as in the previous study of the rounding problem, for example, Fix (PI) =3; fix ( -1.3) =-1; fix (1.3) =1;2)round (n): rounded to the nearest integer, such as round ( -1.3) =-1;round ( -1.52) =-2;round (1.3) =1;round (1.52) =2;round(PI) =3 ; round (3.5) =4;round (-3.5) =-4;Round (-3.1) =-3; This note differs from fix, pay attention to the distinction!3Floor (n), as the name implies, is the flooring,

The difference between the Ceil,floor,round,intval function of PHP's rounding function1, ceil-into a method to take the wholeDescriptionfloat ceil (float $value)Returns the next integer not less than value, in which value is entered if there is a fractional part. The type returned by Ceil () is still float, because the range of float values is usually larger than the integer.Ceil () example

There is a 100-story tall building with the same hardware and software level but two unknown eggs, the two eggs are required to determine which layer is the highest position where the eggs can safely fall with the minimum number of times. The eggs may break down on the first floor or even the fifth floor.
If the layer-l eggs are not broken, and the layer-L + 1 is broken, the layer-L is desired. Because t
We often use the PHP to take the whole function, mainly: Ceil,floor,round,intval.1, Ceil--into a method to take the wholeDescriptionfloat ceil (float value)Returns the next integer not less than value, in which value is entered if there is a fractional part. The type returned by Ceil () is still float, because the range of float values is usually larger than the integer.PHP takes an integer function Example 1. Ceil () exampleEcho Ceil (4.3); // ec
When processing floating point numbers in php, it is often necessary to rounding them. In php, there are two functions that apply to this situation: The floor function, the ceil function, and the round function floor function and the ceil function work together to make the data processed by php more authentic and reliable.

I haven't used the math class for a long time. I cannot remember it clearly, so that I can make mistakes when I read a scjp question. I will refresh my memory today. Remember!
Public class t {public static void main (string [] ARGs) {system. out. println (math. round (-4.1); system. out. println (math. round (-4.8); system. out. println ("---"); system. out. println (math. ceil (-4.8); system. out. println (math. floor (-4.8 ));}}
