Set res to the error function erf⁡(x)\operatorname{erf}(x), the complementary error function erfc⁡(x)=1−erf⁡(x)\operatorname{erfc}(x) = 1 - \operatorname{erf}(x), the scaled complementary error function erfcx⁡(x)=ex2erfc⁡(x)\operatorname{erfcx}(x) = e^{x^2} \operatorname{erfc}(x), or the imaginary error function erfi⁡(x)=−ierf⁡(ix)\operatorname{erfi}(x) = -i \operatorname{erf}(ix).
