Running this code:

<?php

bcscale(10);

error_log(0.5/5);
error_log(0.6/6);
error_log(bcdiv(0.6, 6));
?>

Produces this output:

0.1
0.0:
0.1000000000

I'd expect the second line to be "0.1", not "0.0:". The bcdiv value is correct.

Cannot confirm this on Karmic.

Are you using a 64bit arch? (I'm not)

$ php -r "echo PHP_VERSION; echo PHP_EOL; echo 0.6/6; echo PHP_EOL;"
5.2.6-3ubuntu4.1
0.1

@Daniel: I get the same results as you ( 0.1 ) on Ubuntu Jaunty 9.04 amd64. I also tested morodoch's PHP example code, and it works fine here also:

$ php -r "echo PHP_VERSION; echo PHP_EOL; echo 0.6/6; echo PHP_EOL;"
5.2.6-3ubuntu4.1
0.1
$ echo -e "<?php\nbcscale(10);\nerror_log(0.5/5);\nerror_log(0.6/6);\nerror_log(bcdiv(0.6, 6));\n?>" |php
0.1
0.1
0.1000000000
$

So if this is reproducible, maybe it is only reproducible under Ubuntu Hardy 8.04 ??

Confirmed on Hardy (in an OpenVZ container).

# php -r "echo PHP_VERSION; echo PHP_EOL; echo 0.6/6; echo PHP_EOL;"
5.2.4-2ubuntu5.6
0.0:

Upgrading to a backport therein makes it work again:
# php -r "echo PHP_VERSION; echo PHP_EOL; echo 0.6/6; echo PHP_EOL;"
5.2.9-0ubuntu1~blueyed1
0.1

Downgrading to the released version (from the "hardy" repo) shows the same problem:
# php -r "echo PHP_VERSION; echo PHP_EOL; echo 0.6/6; echo PHP_EOL;"
5.2.4-2ubuntu5
0.0:

Fixed in Karmic/Jaunty.
