- bitlib release 21
- -----------------

-
-
-bitlib is a C library for Lua 5.x that provides bitwise operations. It
-is copyright Reuben Thomas 2000-2006, and is released under the MIT
-license, like Lua (see http://www.lua.org/copyright.html; it's
-basically the same as the BSD license). There is no warranty.
-
-Please report bugs and make suggestions to the email address above, or
-use the LuaForge trackers.
-
-Thanks to John Passaniti for his bitwise operations library, some of
-whose ideas I used, and to Thatcher Ulrich for portability fixes.
-
-
-Installation
-------------
-
-The provided Makefile builds a shared library called bit.so, which can
-be installed on LUA_CPATH and used with require.
-
-
-Use
----
-
-Lua functions provided:
-
-bit.bnot(a) returns the one's complement of a
-bit.band(w1,...) returns the bitwise and of the w's
-bit.bor(w1,...) returns the bitwise or of the w's
-bit.bxor(w1,...) returns the bitwise exclusive or of the w's
-bit.lshift(a,b) returns a shifted left b places
-bit.rshift(a,b) returns a shifted logically right b places
-bit.arshift(a,b) returns a shifted arithmetically right b places
-bit.mod(a,b) returns the integer remainder of a divided by b
-
-All function arguments should be integers. The number of bits
-available for logical operations depends on the data type used to
-represent Lua numbers; this is typically 8-byte IEEE floats, which
-give 53 bits (the size of the mantissa).
-
-The logical operations start with "b" for "bit" to avoid clashing with
-reserved words; although "xor" isn't a reserved word, it seemed better
-to use "bxor" for consistency.
