str
This acts as the single source of truth for type promotion rules. The
promotion logic is designed to be consistent across all backends.
Rule: If any input is a float, the result is float32. Otherwise, the result
is int64 to match NumPy/JAX's default behavior for precision.
A variable number of type objects (e.g., <class 'int'>
,
np.dtype('float32')).
A string representing the promoted dtype.
