Calculate the Euler Number with more decimal places

[Pedroski55]

I was reading about the Euler Number, e.

I read it has been calculated to a trillion decimal places.

I would be happy with 100 decimal places.

I have 15 decimal places.

How could I get more decimal places?

def euler(n):
    print('Potential is:', n)
    inner = 1 + 1/n
    print('inner value is:', inner)
    e = inner**n
    print('e = ', e)
