WebPython number method exp () returns returns exponential of x: e x. Syntax Following is the syntax for exp () method − import math math.exp( x ) Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object. Parameters x − This is a numeric expression. Return Value WebMay 3, 2014 · The obvious solution would be. import math def e (n=10): return sum (1 / float (math.factorial (i)) for i in range (n)) but it loses precision around n=20 (the error as compared to math.e is around 10^-16) 40-digits precision might be a challenge, and might require arbitrary precision arithmetic.
