-1 for i
-1 for forEach rather than map ( the behavior of map is more verbose than modifying an object and expecting it to be modifed in the original array )

If you pass 0.5 to the function, it won't return the negative value;

This is something called regex which is a handy string manipulation module used in nearly all programming languages (Python, JavaScript, Java, C++ etc). It's very useful and I recommend learning it in the future. If you scroll down to the other comments you can see some information about this solution, and a step by step working of it from @bkaes.
