Web26 sep. 2024 · Those two steps are for dividing a 32-bit signed value by another 32-bit signed value. The idiv instruction divides a 64-bit signed integer by a 32-bit integer. Therefore if all you have is a 32-bit integer, you need to convert it to a 64-bit integer first. Why idiv was designed to do a 64-bit by 32-bit Web25 sep. 2011 · So if int is larger than 16-bits, then the result will be a signed 32-bit integer. However, if you assign it back to a 16-bit integer, it will truncate leaving only bottom 16 bits of the two's complement of the new number. So if your definition of "result" is the intermediate immediately following the multiply, then the answer is the size of int.
