It's all about floating point approximation. If you work with floating points, you sometimes get bitten. I was. See Comparison misses a true in *some* cases for example.

Solution: round it off with sprintf.

Update: davorg is right. Stick with integers, or put the sprintf in the for:  $i = sprintf('%.1f', $i - 0.1);
