The following is an example for a 4-bit register. When shifting a signed value, the >> operator is an arithmetic shift.

I am publishing a web tool I created as a hobby. Wikipedia says that C/C++ 'usually' implements an arithmetic shift on signed values. It is free of charge, so please feel free to use it. Enter a number to convert to 32 bit binary, plus the number of spaces to shift to the left, and the tool will return the result after the logical shift. Right shift of a negative signed number has implementation-defined behaviour. Practice your math skills and learn step by step with our math solver.

In both cases, the overflowed rightmost bit disappears, but the way to fill the leftmost empty bit position is different. Then, in the "Steps" field, enter how many digits to shift the number to the left. An "arithmetic" shift leaves the original value in the leftmost bit. Enter a number to convert to 32 bit binary, plus the number of spaces to shift to the right, and the tool will return the result after the arithmetic shift.

That's the point of the question.

Equivalence of arithmetic and logical left shifts and multiplication, Non-equivalence of arithmetic right shift and division, Handling the issue in programming languages, The Verilog arithmetic right shift operator only actually performs an arithmetic shift if the first operand is signed. Bit shifting describes the operation of shifting a string of bits a certain number of positions to the left or the right.
