PHP中计算百分比时如何保证各部和为1?

<br />
$total = $a+$b+$c+$d;<br />
<br />
$percentA = ceil($a*100.0/$total);<br />
$percentB = ceil($b*100.0/$total);<br />
$percentC = ceil($c*100.0/$total);<br />
$percentD = ceil($d*100.0/$total);<br />
<br />


上面的代码似乎无法确保最后的总和是100%

<br />
$percentD = 100-$percentA-$percentB-$percentC;<br />

除了这种方法,有其他方法吗?
