Question

I am pulling 10 integers from a MySQL DB:

I want to be able to determine the largest value then round up to the nearest hundredth. With this I want to then be able to create a list of 10 numbers that are evenly separated down to zero.

In Example :
{ 232, 10, 0, 55, 130, 423, 102, 22, 98, 3 }

Take : 423 => Round up to 500

Then with the number 500 come back with equally separated numbers such as :

500 , 450 , 400, 350, 300, 250, 200, 150, 100, 50, 0

Thank you for the help in advance!

Answer 1

This should do it:

<?php
    $array = array(232, 10, 0, 55, 130, 423, 102, 22, 98, 3); 
    $max = max($array);
    $max_rounded = ceil($max/100)*100;
    $diff = ($max_rounded/10);
    while($max_rounded >= 0){
        echo $max_rounded.' ';
        $max_rounded -= $diff;
    }
?>
