NumPy - exp() function

The NumPy exp() function is used to calculate e raised to the power of given value, i.e., ex. Please note that e is the base of the natural system of logarithms, and its value is approximately 2.718282.


numpy.exp(a, out=None)


a Required. Specify array (array_like) containing elements, of which the exponential is calculated.
out Optional. Specify 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.

Return Value

Returns the exponential of each element of a.


In the example below, numpy exp() function is used to calculate the exponential of each element present in array Arr.

import numpy as np

Arr = np.array([0, 1, 2, 3])

print("The exponential of values:")

The output of the above code will be:

The exponential of values:
[  1.           2.71828183   7.3890561   20.08553692]
