Hi!

    There is the calculation errors for the floating point, so I checked the
PHP website.  On that website, the function webpage, pow().  It said that
"In PHP 4.0.6 and earlier pow() always returned a float, and did not issue
warnings.".  So, there was some changes to the pow() on PHP 4.0.7 and after.
Let's do the demo script.

    echo pow(0, 0.0829);

    It should return a "0" as it did in version 4.0.6 and before.  But
version 4.0.7 and after, it returned a "-1.#IND".  Why is that?  What is the
other way around to fix the problem?  Let me know!

Thanks,
 Scott
