Although bitwise operators are not expected to use with float values,
the reported behaviour is quite inconsistent.
Possible documentation problem?

The Bitwise NOT operator ~ doesn't fuinction correctly on the Linux
system.
Examples:
~-2222222222 = 2147483647
~4180982798 = 2147483647
But on a Windows 2000 Server it functions well:
~-2222222222 = -2072745075
~4180982798 = 113984497
On both systems PHP 4.2.2 is used.
If that's a "feature" then PHP is not usable for any bitwise
operation.
