scipy.special.radian#

scipy.special.radian(d, m, s, out=None) = <ufunc 'radian'>#

Convert from degrees to radians.

Returns the angle given in (d)egrees, (m)inutes, and (s)econds in radians.

Parameters:

darray_like: Degrees, can be real-valued.
marray_like: Minutes, can be real-valued.
sarray_like: Seconds, can be real-valued.
outndarray, optional: Optional output array for the function results.

Returns:

scalar or ndarray: Values of the inputs in radians.

Notes

Array API Standard Support

radian has experimental support for Python Array API Standard compatible backends in addition to NumPy. Please consider testing these features by setting an environment variable SCIPY_ARRAY_API=1 and providing CuPy, PyTorch, JAX, or Dask arrays as array arguments. The following combinations of backend and device (or other capability) are supported.

Library	CPU	GPU
NumPy	✅	n/a
CuPy	n/a	✅
PyTorch	✅	⛔
JAX	⚠️ no JIT	⛔
Dask	✅	n/a

See Support for the array API standard for more information.

Examples

>>> import scipy.special as sc

There are many ways to specify an angle.

>>> sc.radian(90, 0, 0)
1.5707963267948966
>>> sc.radian(0, 60 * 90, 0)
1.5707963267948966
>>> sc.radian(0, 0, 60**2 * 90)
1.5707963267948966

The inputs can be real-valued.

>>> sc.radian(1.5, 0, 0)
0.02617993877991494
>>> sc.radian(1, 30, 0)
0.02617993877991494
