Mmm, I'm not sure if I understand this correctly but I don't think PHP will "just decide" that your string IS a number and *formats* it. Consider this: <?php $var = 1111111111111111; // int $var2 = "1111111111111111"; // str echo $var; // echoes 1.11111111111E+015 echo '<br />'; echo $var2; // echoes 1111111111111111 ?> As you can see, PHP didn't "touch" the string version... Anyway, I don't think the conversion to an exponential notation is peculiar to PHP--my math teacher required me to do the same :) - E __________________________________________________ Do You Yahoo!?
