Functions and classes related to unit conversion

`psychopy.tools.unittools.``radians`(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])

Convert angles from degrees to radians.

Parameters: x (array_like) – Input array in degrees. out (ndarray, None, or tuple of ndarray and None, optional) – A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. where (array_like, optional) – Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone. **kwargs – For other keyword-only arguments, see the ufunc docs. y – The corresponding radian values. ndarray

Examples

Convert a degree array to radians

```>>> deg = np.arange(12.) * 30.
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((deg.shape))
>>> ret is out
True
```
`psychopy.tools.unittools.``degrees`(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])

Convert angles from radians to degrees.

Parameters: x (array_like) – Input array in radians. out (ndarray, None, or tuple of ndarray and None, optional) – A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. where (array_like, optional) – Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone. **kwargs – For other keyword-only arguments, see the ufunc docs. y – The corresponding degree values; if out was supplied this is a reference to it. ndarray of floats

`rad2deg()`
equivalent function

Examples

Convert a radian array to degrees

```>>> rad = np.arange(12.)*np.pi/6
```>>> out = np.zeros((rad.shape))
