Is right shift arithmetic in C?
Arithmetic Right-Shifts
The C standard requires that compilers document their implementation behavior.
Nearly all compilers implement signed shift right as an arithmetic shift that rounds to floor.
This is the simplest and most efficient behavior for the compiler vendor to provide.An arithmetic right shift means that the sign bit is extended to fill the upper bits, whereas a logical right shift uses zeroes to fill the upper bits. 's value, modulus the register size (32 or 64), is used as the shift amount. operation rotates n bits to the right.
