The deg2rad function is used to convert degrees to radians. It comes as part of NumPy, which is a library of the high-level coding language Python.

### Syntax

numpy.deg2rad(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'deg2rad'>


A universal function (ufunc) is a function that operates on ndarrays in an element-by-element fashion. The deg2rad method is a universal function.

### Parameters

The deg2rad function accepts the following arguments.

• x: array-like structure on the contents of which the deg2rad function will be applied. The input array will be in radians.

• out (optional): the function’s output is stored at this location.

• where (optional): if set True, a universal function is calculated at this position.

• casting (optional): enables the user to decide how the data will be cast. If set as same_kind, safe casting will take place.

• order (optional): determines the memory layout of the output. For example, if set as K, the function reads data in the order they are written in memory.

• dtype (optional): the data type of the array.

• subok (optional): to pass subclasses, subokmust be set as True.

### Return value

The deg2rad function returns the corresponding degree values of type float in an ndarray. If the optional out parameter is provided, it returns a reference.

If x is a scalar, the return value is also a scalar.

### Example

The example below demonstrates how to apply the deg2rad function on an array that contains 4 degree values.

import numpy as npdegree=[180, 360, 720, 1440]print(np.deg2rad(degree))
