The absolute simplest way to do this is what you originally had.  I would not 
look further than

    if ($quant<$amount)
       // $quant-$amount is negative

If I were reading your code, I would find both if(($quant-$amount)<0) and 
if(neg_num($quant-$amount)) more obfuscating than if($quant<$amount).
