Without trying it, I would assume php (since it's typeless) would just cast the string back into a number? I wouldn't do it for another reason- possible loss of accuracy.

You will lose your decimal places during normal calculations...

But you can display them back to the user using number_format.


Bear in mind that you should always pass the formatted number into a
different variable as you will NOT be able to perform any further
calculations on the formatted variable since it now considered a string.

Hope this helps

Ok.  I have this resolved.

One more question about this --- is there any way I may keep the 2
decimal places when I use math to manipulate the variable ---

$rate_plan_rate = ($rate_plan_rate / 100) * (100 - $discount);

$ 28.8

I would like the result to be $28.80

Thanks for your help Micah.

If I make a test table with a field that is DECIMAL(4,2), I can:

I get '8.00' from the 'a' field.

It looks like you're using an abstraction library? Perhaps that's the

When I use
$advertisement_rate = mysql_result($rate_plan_result,0,"rate");

$advertisement_rate has a value of 800 instead of 8.00 --- how can I get
my 2 decimal places back?
