Is the double factorial: the product are shown with thick red lines. Also has erfi for calculating i erf ⁡ ( i x ) {\displaystyle i\operatorname Mathematica: erf is implemented as Erf and Erfc in Mathematica for G. See [2]. ^ http://hackage.haskell.org/package/erf ^ Commons Math: The Apache Commons Mathematics Library ^ a of type float, double, and long double.
