Ok guys.. I've looked everywhere and cannot find an explanation
for this behavior. Could you guys explain it? :)
This script returns the same thing on 4.0.4p1 and 4.0.3p1.
/* Anything less than 3.2/-0.32 exhibits this behavior. Anything above it doesn't */
$x = 0.1 * 3.2;
$y = -0.32;
print("$xt$ynn");
$a = $x - $y;
$b = $x + $y;
print("$at$bn");
I can increase the 3.2 and the -0.32 and the return is sane.. everything I've tried
below 3.2 returns this oddity.
Output from above script..
0.32 -0.32
0.64 5.5511151231258E-17
Any clues?
