Just as pont of interest: We also use PHP for our (travel agency..) intra+extranet admin system, and among other things, we use PHP-generated forms to order hotel rooms for our clients. At times we get forms requesting a hotel room for 3.999.. nights :)) Now I know why. Thanks again for all the reactions, and keep up the excellent work! :) Previous Comments: [2004-03-31 10:28:25] [EMAIL PROTECTED] For a computer there is simply no such thing as exactly 0.23, it is as simple as that. When displaying floating point numbers, either use printf() and specify the number of significant digits you want or use PHP's precision setting. As for this suggestion: Maybe a magicless solution would be: don't use greater precision then either the minuend or subtrahend (the one with greatest precision). Reducing precision during the calculation would magnify rounding errors greatly when doing a series of operations on the floating point values. You want to apply lower precision at the end at display time, not during the calculation. And at display time we don't know what the precicion of the operands were that led to this value which is why you need to explicitly express what precision you want values displayed at.

Guys, how in the world is PHP supposed to magically guess what
precision you want results displayed in.
141.23 - 141 _is_ precisely 0.23. If I was asking for 1/3, then I would
understand the decimal places. But how come 141.23-141 turns out to
have so many decimal places in the end instead of just being 0.23 - the
mathematically correct and precise result?

Guys, how in the world is PHP supposed to magically guess what
precision you want results displayed in. If you know you always want
lower precision, set that in your php.ini file. Or if you just want it
temporarily simply do:
$old = ini_set('precision',2);
echo (string)(750 - 749.99);
ini_set('precision',$old);

That is the whole point of the answer. Floating point values are not
accurate and are not nice. And we do not do a bunch of work just to
make them look better in certain circumstances.
[2004-03-30 12:07:45] garbo_doe at hotmail dot com
IMHO I think this is a bug. Of course there are problems with
floatingpoint values in binary form, especially when rounded many
times. But in an operation like ?php echo (string)(750 - 749.99) ? it
shouldn't return 0.00 but 0.01.
I did a quick test in Delphi: showmessage(floattostr(750 - 749.99));
returns 0.01, not 0.00.
I had to solve it in PHP but multiplying with 100, then subtract and
then divide the result by 100 again.
It's not pretty :-D
(0.00999[infinite 9's] IS exactly the same as 0.01, but it should
remember the infinite with a bit or something, so (1/3)*3 = 1 and not
0.9)
(this is similar as bug #8164)
[2004-03-29 01:06:46] [EMAIL PROTECTED]
Floating point values have a limited precision. Hence a value might
not have the same string representation after any processing. That also
includes writing a floating point value in your script and directly
printing it without any mathematical operations.
Thank you for your interest in PHP.

#26618 [Opn]: Using % % tags makes include() not to work (sometimes)
