  in math, if you have a real and you round it, it’s always a real not an integer.

  No, that’s made up. Outside of very specific niche contexts the concept of a number having a single well-defined type isn’t relevant in math like it is in programming. The number 1 is almost always considered both an integer and a real number.

  If we follow your mind with abs(-1) of an integer it should return a unsigned and that makes no sense.

  How does that not make sense? abs is always a nonnegative integer value, why couldn’t it be an unsigned int?

    I’m ok with that, but what I mean is that it makes no sense to change the type of the provided variable if in mathematics the type can be the same.

  What? In math, integers can be negative.
