PHP rounding function (floor, ceil, round, intval)_PHP tutorial

There are four rounding functions in PHP, such as floor, ceil, round, and intval. Below, I will introduce application examples of each of them.

floor rounding by rounding Syntax format: float floor (float value)

Returns the next integer not greater than value, and rounds the decimal part of value. The type returned by floor() is still float because the range of float values ​​is usually larger than that of integer.

The code is as follows

代码如下	复制代码
echo floor(4.3); // 4 echo floor(9.999); // 9

Copy code

echo floor(4.3); // 4 echo floor(9.999); // 9

代码如下	复制代码
echo ceil(4.3); // 5 echo ceil(9.999); // 10

ceil round to the nearest integer

Syntax format: float ceil (float value)

Returns the next integer that is not less than value. If value has a decimal part, it is rounded up by one. The type returned by ceil() is still float, because the range of float values ​​is usually larger than that of integer

代码如下	复制代码
echo round(3.4); // 3 echo round(3.5); // 4 echo round(3.6); // 4 echo round(3.6, 0); // 4 echo round(1.95583, 2); // 1.96 echo round(1241757, -3); // 1242000

round Rounds floating point numbers

The code is as follows

Copy code

echo ceil(4.3); // 5 echo ceil(9.999); // 10

代码如下	复制代码
echo intval(4.3); //4 echo intval(4.6); // 4 ?>

Syntax: float round ( float val [, int precision] )

The code is as follows

Copy code

echo round(3.4); // 3 echo round(3.5); // 4 echo round(3.6); // 4 echo round(3.6, 0); // 4 echo round(1.95583, 2); // 1.96 echo round(1241757, -3); // 1242000 intval---convert variables into integer types

Example intval()

The code is as follows	Copy code
<🎜>echo intval(4.3); //4<🎜> <🎜>echo intval(4.6); // 4 <🎜> <🎜>?> http://www.bkjia.com/PHPjc/632727.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/632727.htmlTechArticleThere are four rounding functions in php, such as floor, ceil, round, intval.
