That's nothing different, but exactly the same problem as I described
from the beginning.
This is the function that I currently use as a workaround. It works
fine, but I would prefer php doing this itself...
function my_number_format ($number, $decimals=0, $dec_point=',',
$thousands_sep='.') {
$string = number_format($number, $decimals, $dec_point,
$thousands_sep);
$pos = strlen($string) - 1;
$increase = false;
while ($pos >= 0) {
if (($increase) and (is_numeric($string{$pos}))) {
$string{$pos} = chr(ord($string{$pos}) + 1);
$increase = false;
}
if ($string{$pos} == ':') {
$string{$pos} = '0';
$increase = true;
}
$pos--;
}
if ($increase)
$string = '1' . $string;
return $string;
}

For the garbage problem, that's something else.
Can you provide a reproduce script (with data) please?

this sure IS a bug, scott_mac you need to wake up, if this is the best
that php handles floating point then it is worthless. In reading a value
of "19" from an excel spreadsheet via odbc, it formats it as "18.:0"
which is pure garbage and a bug to me. How can you defend that?
I can send my code if you want.

scott@skinny [~] $ php -r 'var_dump(number_format(3.9, 2));'
string(4) "3.90"
Can't reproduce this on Linux.

I don't think it's a problem with limited precision but rather about
the function itself. I think a float should be able to represent 3
digits without a problem. The hex representation of the float that is to
be formatted is 0x40799998, which equals to about 3.8999996.
I think number_format should be able to round this to '3.90' instead of
displaying it as '3.8:'
