# scipy.special.exp2

scipy.special.exp2(x, out=None) = <ufunc 'exp2'>

  Compute `2**x` element-wise.

  Parameters:
    xarray_like

      x must contain real numbers.

    outndarray, optional

      Optional output array for the function values

  Returns:
    scalar or ndarray

      `2**x`, computed element-wise.

  Examples

      >>> import numpy as np
      >>> from scipy.special import exp2

      >>> exp2(3)
      8.0
      >>> x = np.array([[-1, -0.5, 0], [0.5, 1, 1.5]])
      >>> exp2(x)
      array([[ 0.5       ,  0.70710678,  1.        ],
             [ 1.41421356,  2.        ,  2.82842712]])
