Re: [PHP-DB] detecting negative numbers
No, I get it. I just thought that there might have been some built in
function like if(neg_num($quant - $amount))
or something like that. I know how to do it, but I thought that there might
have been an alternate method. Just because I asked a simple question
doesn't mean I'm stupid, I'm just curious if there is a simpler way to do an
already simple task.

Not sure which way around you want it, but I think this is what you are
after...
if (($quant - $amount) < 0)
{
echo "You don't have that many!";
}
I don't mean any offense, but the possibility that someone who couldn't
figure that out is writing PHP code scares me. You might want to think
about Googling for an absolute beginners guide to programming before
continuing.

Re: [PHP-DB] detecting negative numbers
They are both positive numbers. I want to see if, when subtract, do they
equal a negative number?

I'm not sure which "result" you are refering to, but this echo's if:
$quant is greater than $amount
$amount is less than 0
$quant is less than 0
if ($quant > $amount or $amount < 0 or $quant < 0) {
echo "You don't have that many!";
}

$quant is the user inputted amount and $amount is the amount that they
actually have. Is there any way of checking if the result is negative rather
than doing what I have above?

[PHP-DB] detecting negative numbers
Currently I have this:
if($quant > $amount) {echo "You don't have that many!"; }
$quant is the user inputted amount and $amount is the amount that they
actually have. Is there any way of checking if the result is negative rather
than doing what I have above?
