Ramanujan: Twelve Lectures on Subjects Suggested by His Life and Work, 3rd ed. Using the alternate value a≈0.147 reduces the maximum error to about 0.00012.[12] This approximation can also be inverted to calculate the inverse error function: erf − 1 ⁡ ( x ) However, it can be extended to the disk |z| < 1 of the complex plane, using the Maclaurin series erf − 1 ⁡ ( z ) = ∑ k = 0

This usage is similar to the Q-function, which in fact can be written in terms of the error function. Error function From Wikipedia, the free encyclopedia Jump to: navigation, search Plot of the error function In mathematics, the error function (also called the Gauss error function) is a special function For previous versions or for complex arguments, SciPy includes implementations of erf, erfc, erfi, and related functions for complex arguments in scipy.special.[21] A complex-argument erf is also in the arbitrary-precision arithmetic Softw., 19 (1): 22–32, doi:10.1145/151271.151273 ^ Zaghloul, M.
