Re: PHP 4.2.2 Float->Mysql addition problem

It's possible that MySQL has larger range of floats than PHP. Then when your numbers come in, PHP ends up making them be things like: 'NaN' (not a number) or '6.02e+23' or ... There are a LOT of ways to represent floats in such a way that you can confuse the heck out of PHP and MySQL between the two of them. You really need to figure out where/how your calculcations should be made to get the sort of range and precision you need.
