经测试 round 取整不会连续进位,只进一位。如果想连续进位,就自己处理了 如: $hourbbnum=0.49024;$hourbbnum=number_format($hourbbnum,2,'.','');$hourarr=explode(.,$hourbbnum);if(floatval($hourarr[1])=45){$hourbbnum=$hourarr[0]+1;}else{$hourbbn

如:

$hourbbnum = 0.49024;
$hourbbnum = number_format($hourbbnum, 2, '.', '');
$hourarr =  explode(".",$hourbbnum);
if(floatval($hourarr[1])>=45)
{
	$hourbbnum = $hourarr[0]+1;
}else{
	$hourbbnum = $hourarr[0];
}
echo hourbbnum;
