WebOct 1, 2010 · What you are asking is essentially not why there are bitshift operators in C#/Java, but why the javac compiler doesn't optimize multiplications and divisions with powers of two into bitshifts. The knee-jerk reaction to this is that multiplication and division have different semantics than bitshifts, so it does not map 100% to replace the ... WebMar 12, 2015 · 1. Manually implemented.
