Simple sample code for PHP math functions

A small example of a PHP math function-bbs.it-home.org Echo ABS (-1);//Take absolute value function echo " ####### #ceil, floor function ###### "; echo ceil (1);//Take the smallest integer greater than the parameter Echo Ceil (-1.1); echo " "; Echo Floor (1.1);//Take the maximum integer less than the parameter Echo Floor (-1.1); echo " ####### #max函数 ###### "; echo Max (+//) Take 1 and 2 maximum echo " "; $arr =array (1,2,3,4,5,7,6); echo Max ($arr);//The maximum value in an integer array echo " ####### #pow函数 ###### "; Echo Pow (5,2);//Output 5 2-time value echo " ####### #round函数 ###### "; Echo round (1.511);//Rounding function echo " ####### #rand函数 ###### "; for ($i =0; $i <1000; $i + +) { $temp =rand (0,9), or//Take an integer value from 0 to 9, which can be taken to the upper and lower values /* if ($temp ==0) { echo "can take the value of the lower limit"; Break } */ if ($temp ==9) { echo "can fetch the upper limit value"; Break } } ?> Copy Code
