Calculating the value of e is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.


Calculate the value of e. See details: Calculating the value of e

decimals(14)

for n = 1 to 100000 

    e = pow((1 + 1/n),n)

next see "Calculating the value of e with method #1:" + nl see "e = " + e + nl

e = 0 for n = 0 to 12 

    e = e + (1 / factorial(n))

next see "Calculating the value of e with method #2:" + nl see "e = " + e + nl

func factorial(n) 

      if n = 0 or n = 1 
         return 1 
      else
         return n * factorial(n-1)
      ok

Calculating the value of e with method #1:
e = 2.71826823719230
Calculating the value of e with method #2:
