chainer.functions.cast¶

chainer.functions.cast(x, typ)[source]¶

Cast an input variable to a given type.

Parameters:	x (`Variable` or `numpy.ndarray` or `cupy.ndarray`) – Input variable to be casted. A \((s_1, s_2, ..., s_N)\)-shaped float array. typ (`str` of dtype or `numpy.dtype`) – Typecode or data type to cast.
Returns:	Variable holding a casted array.
Return type:	Variable

Example

>>> x = np.arange(0, 3, dtype=np.float64)
>>> x.dtype
dtype('float64')
>>> y = F.cast(x, np.float32)
>>> y.dtype
dtype('float32')
>>> y = F.cast(x, 'float16')
>>> y.dtype
dtype('float16')
