Re: [office-comment] BASE(): support two's complement negative binary numbers

Two's complement requires knowing the integer memory size.  For example, the 8 bit two's complement number equivalent to -1 is 0xFF, but if that is a 16 bit number, then that is 255. 

How does BASE know the integer size for determining what the two's complement is? 

The machine size would give different results if a the spreadsheet is on a 32 bit machine or a 64 bit machine.
