## How can I use “e” (Euler’s number) and power operation in python 2.7

You can use exp(x) function of math library, which is same as e^x. Hence you may write your code as: I have modified the equation by replacing 1/2 as 0.5. Else for Python <2.7, we’ll have to explicitly type cast the division value to float because Python round of the result of division of two …

## What exactly does numpy.exp() do? [closed]

The exponential function is e^x where e is a mathematical constant called Euler’s number, approximately 2.718281. This value has a close mathematical relationship with pi and the slope of the curve e^x is equal to its value at every point. np.exp() calculates e^x for each value of x in your input array.
