hi there,
I know that is possible to make numbers 1.3 to convert to ~1 (2.6 ~ 3 etc...)
But is it possible to change them to higher side when they are 1.1 ; 1.2; 1.3, 5.1, They would be like 1; 1; 1; 5;
If you need more specific details, ask :) thanks

Looks like you contradicted yourself. You said "higher side", but then you rounded them down, do you mean:

If you have 1.2 it will go to 2?

If so, handy function:



<?php
$number = 1.2;

$number = ceil($number);
echo $number; // Ouputs 2
?>


Or if you mean the opposite:



<?php
$number = 1.8;

$number = floor($number);
echo $number; // Ouputs 1
?>


Or if you mean just rounding in general:



<?php
$number = 1.8;

$number = round($number);
echo $number; // Ouputs 2
?>


Hopefully one of the above is what you want. If not, just say.

See:

http://php.net/manual/en/function.round.php

particularly:


Example #1 round() examples
<?php
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
echo round(5.045, 2); // 5.05
echo round(5.055, 2); // 5.06
?>



Example #2 mode() examples
<?php
echo round(9.5, 0, PHP_ROUND_HALF_UP); // 10
echo round(9.5, 0, PHP_ROUND_HALF_DOWN); // 9
echo round(9.5, 0, PHP_ROUND_HALF_EVEN); // 10
echo round(9.5, 0, PHP_ROUND_HALF_ODD); // 9

echo round(8.5, 0, PHP_ROUND_HALF_UP); // 9
echo round(8.5, 0, PHP_ROUND_HALF_DOWN); // 8
echo round(8.5, 0, PHP_ROUND_HALF_EVEN); // 8
echo round(8.5, 0, PHP_ROUND_HALF_ODD); // 9
?>

So I image you would want something like:


$number = round($number, 2, PHP_ROUND_HALF_DOWN);

or:


$number = round($number, 2);

perhaps even:


$number = 33.333333;
$number = ceil($number*100);
echo $number/100;
