The result of 512*1024 becomes 0

That doesn't mean you should use "k = 524288" in your code because people reading the code will have a hard time figuring out why you are using that value. Good programming practice would be for the 1024 constant to have a useful name and the 512 constant to have a useful name.

I took that to be a sign of this being a MRE.
