WebConsistent semantics across 16, 32 and 64 bit platforms. Supports different lua_Number types: either IEEE 754 doubles, int32_t or int64_t. Runs on Linux, *BSD, Mac OS X, Windows and probably anything else you can find. WebIt remaps bit-band alias addresses to the bit-band region. For reads, it extracts the requested bit from the read byte, and returns this in the Least Significant Bit (LSB) of the read data returned to the core.. For writes, it converts the write to an atomic read-modify-write operation.

Seems strange, doesn't it. If the HSION bit is set, then its address in the bit-band region contains the value 0x00000001 (a 4-byte location for every aliased bit); if it is reset, then the corresponding value in the bit-band region is 0x00000000.
