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;
结果: 1
