WebMy goal is just squaring a value so is there a way to define a “multiply” circuit acting only on the bits storing the value to be squared and then store that value in a new register. This would amount to finding some kind of mapping between the locations of the 1s in the bitstring we want to multiply to the locations of 1s in the result. WebSep 7, 2013 · You can't by bit-shifting alone. Bit-shifting a binary number can only multiply or divide by powers of 2, exactly as you say. Similarly, you can only multiply or divide a decimal number by powers of 10 by place-shifting (e.g. 3 can become 30, 300, 0.3, or 0.03, but never 0.02 or 99).
