WebJul 28, 2024 · First, what bits are "shifted in"? Zeroes are shifted in from one side (i.e. 0b1110_1010u8 << 4 == 0b1010_0000u8 ), or the bits rotate (i.e. 0b1110_1010u8 << 4 == 0b1010_1110u8 ), or it's unspecified (like overflowing behavior of integers is unspecified), or something else. Additionally, how does shifts work with signed integers? http://www.uwenku.com/question/p-fqyzrrjl-bam.html

C = bitshift (A,k,n) returns the value of A shifted by k bits. If k&gt;0, this is same as a multiplication by 2k (left shift). If k&lt;0, this is the same as a division by 2k (right shift). An equivalent computation for this function is. C = fix (A*2^k). If the shift causes C to overflow n bits, the overflowing bits are dropped.

WebThe unsigned right shift operator " &gt;&gt;&gt; " shifts a zero into the leftmost position, while the leftmost position after "&gt;&gt;" depends on sign extension.
