Php_ keep two decimal places and round _ Keep two decimal places and do not round
php reserved Two decimal places and rounded
$num = 123213.666666;echo sprintf ("%.2f", $num);



PHP retains two decimal places and does not round
$num = 123213.666666;echo sprintf ("%.2f", substr (sprintf ("%.3f", $num), 0,-2));


php into a method to take the whole
echo ceil (4.3);    5echo ceil (9.999);  10


php House de method, take integer
echo floor (4.3);   4echo floor (9.999); 9

Echo round (123213.666666,2);
Echo Number_format ((ceil (123213.666666 * 100))/100,2, '. ', ');
SUBSTR efficiency is poor. Wouldn't it be easier to do that?
It is recommended to read more manuals.
