I have found a bug on page function.fread.html
[chm date: 2002-04-20]...
in php 4.2.1 pow function
if code is following will show correct result
$a=1;
$b=0.8;
echo pow($a,$b);

btw, if ($a or $b) from db query, will show wrang message and show incorrect result

i will test it, may translate ($a or $b) to math type will be show correct, may be variable type problem in php 4.2.1 pow function

above 2 examples will not't show wrang message and show correct result in php 4.1.2
