- Julia: Includes erf and erfc for real and complex arguments.
- C++: C++11 provides erf() and erfc() in the header cmath.
- 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
- For any complex number z: erf ( z ¯ ) = erf ( z ) ¯ {\displaystyle \operatorname − 0 ({\overline 9})={\overline {\operatorname 8 (z)}}} where z
