New Comment:
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.
No bug.

If it's not clear already, if you remove the (int) cast, you get
float(3); if the cast is there, it's int(2). This may be some sort of
obscure floating point rounding error.

Set this into the function when declaring it:
TimeToText(1072224000);
And you will get the expected/actual result I defined.

Description:
------------
When attempting to take a float variable and typecasting it into an
int, I receive a magnificent error that is unexplainable.
Reproduce code:
---------------
function TimeToText($timestamp)
{
$day = strftime("%d", $timestamp);
$factor = $day/10;
$factor = (int)(($factor- ((int)($factor)))*10);
var_dump($factor);
}
Expected result:
----------------
int(3)
Actual result:
--------------
int(2)
Instead of truncating all decimal places, converting a float into an
int is changing the entire whole-number value!
