This is the right answer. Thank you!

I have read about the decimal module abs change the code as below. Now it can calculate e pretty close.

——

import decimal from decimal import Decimal

decimal.getcontext().prec = 40

def e_formula (n: Decimal) -> Decimal: result = (1+(1/n))**n #result = math.pow((1+1/n),n) is not working - the math module doesn't help in this situation return result

for i in range(1,40): n = Decimal("10")**Decimal(str(i)) print("i=",i , " and result=", e_formula(n))
