Would it make sense to just have one function, and take the Q number as a
function or template argument instead?

Yes maybe... though I'm thinking that the internal structs containing numbers in
these formats could be converted to use floats instead. So, I'll leave as is for
now. If I find the need for another one, I promise to change it.
