dpnp.radians

dpnp.radians = <DPNPUnaryFunc 'radians'>

Convert angles from degrees to radians for each element \(x_i\) for input array x.

For full documentation refer to numpy.radians.

Parameters:

  • x ({dpnp.ndarray, usm_ndarray}) -- Input array, expected to have a real-valued floating-point data type.

  • out ({None, dpnp.ndarray, usm_ndarray, tuple of ndarray}, optional) --

    Output array to populate. Array must have the correct shape and the expected data type. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

    Default: None.

  • order ({None, "C", "F", "A", "K"}, optional) --

    Memory layout of the newly output array, if parameter out is None.

    Default: "K".

Returns:

out -- An array containing the element-wise angle in radians. The data type of the returned array is determined by the Type Promotion Rules.

Return type:

dpnp.ndarray

Limitations

Parameters where and subok are supported with their default values. Keyword argument kwargs is currently unsupported. Otherwise NotImplementedError exception will be raised.

Notes

The mathematical definition is

\[\operatorname{radians}(x) = \frac{x * \pi}{180}\]

Examples

>>> import dpnp as np
>>> deg = np.arange(12.) * 30.

Convert a degree array to radians:

>>> np.radians(deg)
array([0.        , 0.52359878, 1.04719755, 1.57079633, 2.0943951 ,
       2.61799388, 3.14159265, 3.66519143, 4.1887902 , 4.71238898,
       5.23598776, 5.75958653])

>>> out = np.zeros_like(deg)
>>> ret = np.radians(deg, out)
>>> ret is out
True
