这里统计了php中大量的四舍五入函数,包括有round(),ceil(),floor()等,有需要的朋友参考一下。
代码如下 | 复制代码 |
$s = rand(100,200); $pi=pi(); $r=sqrt($s/$pi); $qz1=round($r); //四舍五入取整 $qz2=ceil($r); //进一法取整 $qz3=floor($r); //舍去法取整 echo "随机产生的圆的面积为:".$s." "; echo "通过除法和开方计算出的圆的半径为:".$r." "; echo "四舍五入取整后:".$qz1." "; echo "进一法取整后:".$qz2." "; echo "舍去法取整后:".$qz3." "; ?> |
