maclaurin_binomial is a function to compute(1+x)^m using maclaurin
binomial series and the interval of convergence is -1 < x < 1
(1+x)^m = 1 + mx + m(m-1)x^2/2! + m(m-1)(m-2)x^3/3!...........
note: if m is a nonegative integer the binomial is a polynomial of
degree m and it is valid on -inf < x < +inf,thus, the error function
will not be valid.
