The imaginary error function has a very similar Maclaurin series, which is: erfi ( z ) = 2 π ∑ n = 0 ∞ z 2 n + 1 n The error function is a special case of the Mittag-Leffler function, and can also be expressed as a confluent hypergeometric function (Kummer's function): erf ( x ) = 2 x ISBN 978-0-486-61272-0.

Error Function Calculator When erf(x) is close to 1, then 1 - erf(x) is a small number and might be rounded down to 0. Complementary Error Function Table Properties[edit] Plots in the complex plane Integrand exp(−z2) erf(z) The property erf ( − z ) = − erf ( z ) {\displaystyle \operatorname − 6 (-z)=-\operatorname − 5

Taylor series[edit] The error function is an entire function; it has no singularities (except that at infinity) and its Taylor expansion always converges. http://jamisonsoftware.com/error-function/gaussian-error-function-erf.php Continued Fractions.

Acton, F.S. click site Also has erfi for calculating i erf ( i x ) {\displaystyle i\operatorname {erf} (ix)} Maple: Maple implements both erf and erfc for real and complex arguments.

The defining integral cannot be evaluated in closed form in terms of elementary functions, but by expanding the integrand e−z2 into its Maclaurin series and integrating term by term, one obtains Erf(1) ISBN978-1-4020-6948-2. ^ Winitzki, Sergei (6 February 2008). "A handy approximation for the error function and its inverse" (PDF). Despite the name "imaginary error function", erfi ( x ) {\displaystyle \operatorname 8 (x)} is real when x is real.
