Bug Type: *Math Functions
Operating System: Win7
PHP Version: 5.3.1
New Comment:
Can you try to isolate the value which causes problems and pass it
directly to number_format? That will be easier to debug and fix.
Can you aslo try using 5.3.2RC2 (VC9 builds if possible, via CLI or
using apachelounge.com's apache).

/*
set up an Excel 97-2003 spreadsheet with a worksheet 'Nov'
and the row headers below on row 3
then add a row 14 with "John Smith" in Tenant, "11" in Lot, and "19" in
Late Fee.
Late fee should be number format with 2 decimals and comma thousands
separator format.
Create an odbc system DSN called "rent_2009" linked to it.
Then run this script against it, I have stripped it down but I think it
will show the problem.
note this will NOT show the problem if you just supply variable values
directly, it has to come
from excel and has something to do with the (string) casting of values
that excel thinks are numbers.
somehow the float and string are getting goofed up. Even when I fixed
the value, the total it was
being added to still had the problem until I hardwired a second test on
"18.:0" to fix that. Jeez.

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.
