You guys are going to love this. I found something that I found quite disturbing.
$test1 = intVal(1999);
$amount = 19.99 * 100;
$test2 = intVal($amount);
$test3 = intVal("$amount");
echo $test1 . "<br />\n";
echo $test2 . "<br />\n";
echo $test3 . "<br />\n";
expected output:
1999
1999
1999
actual output
1999
1998
1999
Appears to be a floating point issue, but the number 1999 is the only number that I was able to get
to do this. 19.99 is the price of many things, and for our purpose we must pass it as 1999 instead
of 19.99.
