It could be a fixed-point type.  If so, knowing that it's 16 bits
doesn't necessarily tell us that it can hold all values from -180 to
180.

To the original poster: How exactly is Real declared?

If the target type can hold all the expected values, just do a
conversion.  If it can't, there's nothing you can do to make all the
values fit (unless you change the type).

We must do something.  This is something.  Therefore, we must do this.
