这样使用while循环很奇怪?
PHP code<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> $pnum=91; $randNum=0; while($pnum>18){ $randNum=$pnum/2; if($randNum
我的本意是想获取比18小的数字,
可是,得出的是45.5?
请问错在哪里?
------解决方案--------------------while这样用:
$pnum = 91;
while($pnum >= 18){
$pnum /= 2;
}
echo $pnum;
------解决方案--------------------死的不能在死的循环。
我的本意是想获取比18小的数字??你的这个是什么需求?有点糊涂
PHP code $pnum=91; $randNum=0; while($pnum>18){ $randNum = $pnum = $pnum/2; if($randNum
