Rounding a number queried from a database

Posted on 16th Feb 2014 07:03 pm by admin

I know that to display a rounded number you just do echo "round($number)";. But how would I convert the $number varible into a rounded number, so that when I say echo "$number"; the rounded number shows up? For example I have a calculation that calculates the distance between two locations using longitude and latitude. $distance is the final result. But $distance is a very long decimal number. To do further calculations with it, I would like to round $distance so that it has no decimal places anymore (So 1482.894736593 would = 1483). So $distance would now equal 1483, not 1482.894736593. Then I could go on and calculate the time, cost, etc. and $number will stay rounded.

Do you know what I am saying?
