WebApr 8, 2024 · It's easier to read the MSB of the input, then left-shift the input left-shift the input with add same,same and repeat. So we read bits starting with the top bit, and construct the result starting with its MSB. (We left shift 1 bit at a time into the destination with ADD to left shift, and a conditional add to set the new bit position or not.) WebMay 30, 2010 · For example, if you want to shift a bit 23 decimal places to the left, one would expect you to enter a 1, then press Lsh, then type 23. But what really happens is it gets shifted 35 bits (23h = 35 decimal.) So, if you really want to shift 23 decimal bits the magic number to enter (after pressing the Lsh key) is 17. WebAn integer is usually 32-bits or 64-bits long, for example. An important thing to keep in mind is that shifting by 1 to the left is the same as multiplying by 2, while shifting to the right by 1 is the same as dividing by 2 then rounding down.
