ceil() doesn't appear work for very small numbers

[gahorth]

Using ceil() on a number such as "0.09" returns zero, but should return 1. PHP's ceil() function returns 1 for a float value of 0.09.

eg.

$num = Decimal::create(0.09000,5)->ceil();  //$num = 0 (should be 1)
$num = Decimal::create(0.00001,5)->ceil();  //$num = 0 (should be 1)
$num = Decimal::create(1.00001,5)->ceil();  //$num = 1 (should be 2)
$num = ceil(0.09);  //$num = 1 (correct)
$num = ceil(0.00001);  //$num = 1 (correct)
$num = ceil(1.00001);  //$num = 2 (correct)

Is this a bug or am I doing something wrong?

That's definitely a bug.
I think the casting to scale 0 (integers) is happening too soon, so the last digits are cut off, thus making the ceil() being applied to the wrong value.

I whipped sth up here: php-collective/decimal-object#18
