Performing a math operation X amount of times

Hey, so I'm doing a thing where I have a number (let's take 256 as an example for ease of use), and I want to halve that number X amount of times, with X ideally being queried with a basic ?{halve how many times|0} prompt. Meaning if I entered 3, for example, the performed calculation would be [[(((256/2)/2)/2)]] with a result of 32. Is that even possible without API functionality? I have no idea how to start approaching it, as I can't find a way to perform an operation like that a variable amount of times while taking the results from previous iterations into account.

There's no way to do general iteration, but for that particular operation, you could use: [[256/2**?{number of halvings}]] That would basically raise the power of the divisor by 1 for each number of halvings: 2, 4, 8, 16... You could also prompt for the dividend: [[?{base number}/2**?{number of halvings}]] There are ways to handle other basic operations, but I don't know if you need those.
