Bit shifts help … WebJan 31, 2013 · 1. You can shift by 0 through 31 (inclusive) bit positions on MIPS. Only 5 least significant bits of the shift count are used in shift instructions. Check your MIPS documentation. If you want to shift by more than 31 positions, you need to break your shift into a series of smaller shifts each of which shifts by 31 or fewer positions. rcgp online servicesWebMay 19, 2024 · As mentioned by others, when right shifting on a signed int, it is implementation defined whether you will get 1s or 0s. In your case, because the left most bit in 1000 is a 1, the "replacement bits" are also 1. Assuming you must work with signed ints, in order to get rid of it, you can apply a bitmask.

In C#, this is not what happens. Instead, the shift count is effectively interpreted mod the register width, so it is impossible to definitively make the register zero using shifts. This is a pain.
