WebJan 5, 2008 · The best way to understand whats happening when u cast unsigned to signed you really need to look up information on 2s compliment. If you HAD to perform a shift, you would need to do it manually. Ex: shiftedUnsignedVar = (unsigned int) (signedVar + 32768); or. shiftedSignedVar = (int) (unsignedVar - 32768); Web16-bit architecture. The MIT Whirlwind (c. 1951) was quite possibly the first-ever 16-bit computer. It was an unusual word size for the era; most systems used six-bit character code and used a word length of some multiple of 6-bits. This changed with the effort to introduce ASCII, which used a 7-bit code and naturally led to the use of an 8-bit multiple which could …
