Rounding?

[[D]Vincent]

How would you get a number to round if it went into a decimal, like let's say I have 100.2, how would i get that to automatically go to 100? Or is there not a way?

PHP's round() function, or sprintf() for older versions.

Thanks ^^

But umm.. with the round how would I use it? Like how would I get it to know that it goes a decimal over to round up to the nearest 1?

You can use something like this:

PHP Code:

// round number up
$roundedup = ceil($number);

// round number down
$roundeddown = floor($number);

// round to nearest
$roundednearest = round($number);

Vincent]So if I did

PHP Code:

$blah1 = $blah2 * "1.2"; 


And $blah1 ended up being let's say 366.6 and I did

PHP Code:

 $blah = round($blah1); 


then it would round it to 367 correct?

Correct. The round() function will always go to the nearest integer, while ceil() and floor() round up and down, respectively.

What if blah1 ended up being 205 and didn't have a decimal? Then what would happen?

If the number you are rounding is already an integer, it will stay the same.
