mindspore.numpy.promote_types

mindspore.numpy.promote_types(type1, type2)

Returns the data type with the smallest size and smallest scalar kind.

Note

The promotion rule is slightly different from original Numpy, but more like jax, due to the preference on 32-bit over 64-bit data types.

Parameters

• type1 (Union[mindspore.dtype, str]) – First data type.

• type2 (Union[mindspore.dtype, str]) – Second data type.

Returns

The promoted data type.

Raises

TypeError – If the input are not valid mindspore.dtype input.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore.numpy as np
>>> output = np.promote_types(np.float32, np.float64)
>>> print(output)
Float64
