Printing a variable with %.2f should output the number with 2 decimals. After upgrading to 4.3.10 it now outputs 3 decimals. %.1f outputs with 2 decimals and I haven't figured out how to print out just 1 decimal (%.0f doesn't work), so I'm treating this as a bug.

This works fine here:

$ php-4.3dev -r 'echo sprintf("%.2f", 42.1231213123);'

42.12

I've tried it under PHP 4.3.10/Linux 2.6 and PHP 4.3.8/WinXPsp2, works as it should.

Could you test with "_%.2f_", just to get sure the last digit isn't coming from somewhere else in your code?

works fine.

I'm sorry, I should have given you more details. The problem doesn't seem to be printf() itself, but where I used it. I was using the following code:
"Rating: <b><?=printf("%.2f", $rating)?></b>"
which worked fine in 4.3.4, but when we upgraded to 4.3.10 it produced the stated error. I've updated all my code to
"Rating: <b><?php printf("%.2f", $rating)?></b>"
which works fine. I probably shouldn't have used printf() inside a <?= ?> in the first place, but it worked fine in 4.3.4 and not in 4.3.10, that's why I reported it as a bug.

Sorry for wasting your time.
