its the good old binary/decimal rounding issue
$result is internally something like e.g.14497.999999999998
when using plain echo rounding will be applied (see php.ini 'precision')
while sprintf "%d" does not round but will cut of all decimals
sprintf("%d",round($result)) should work find

Sometimes when trying to multiply a float and a int then print the result out with
sprintf there is a error in the computation.
The following code produces the incorrect output:
<?
$val1 = 144.98;
$result = ($val1 * 100);
echo $result . "n"; ## Correct output '14498'
echo sprintf ("%10dn", $result); ## Incorrect output '14497'
?>
Not sure if there is something obvious that I am missing? Any help would be
appreciated.
My config line:
./configure --with-mysql=/usr --with-apxs=/usr/sbin/apxs --with-gd=/usr/local
--enable-trans-sid --enable-track-vars --enable-bcmath --with-ttf
