The error function is also known as the Gauss Error Function. The error function for input x is defined as:

erf(x)=2π∫0xe−t2dtWhere x is the input to the calculator\text{erf} (x) = \frac{2}{\sqrt{\pi}}\int_{0}^{x}e^{-t^2}dt\newline\newline \text{Where $x$ is the input to the calculator}

The error function is closely related to the complementary error function erfc

erfc(x)=1−erf(x)\text{erfc} (x) = 1 - \text{erf}(x)
