Consider the following code: $BB = -2181087916; $AA = (int)$BB; $AA = intval($BB); On some systems, $AA will be int(-2147483648), which is actually consistent with the documentation. On most systems, however, $AA will be int(2113879380), which is the same value truncated at 32 bits. I actually need the latter behavior, as it needs to duplicate Delphi code, which, like C, behaves the same way. This is encryption code that does a bunch of calculations on signed 32-bit numbers and ignores any overflows. Any ideas how I can do this? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
