In the lowering we don't have `SymFloat` and `SymInt`, we just have `sympy.Expr` so it is impossible to accurately determine the expected dtype of a `full` call. For example, `sym_float(int_expr)` has `is_integer=True` but should be treated as a float. In the decomposition though, we can get this right. [ghstack-poisoned]
