I presume you mean $$\int e^{-x^2} dx$$. The function $$e^{-x^2}$$ is the Gaussian function, and the integral is called the Gaussian integral.

Yeah a Gaussian so it's a type of Normal Distribution . The "type" meaning, a normal distribution with certain values for the parameters.

It seemed to have a different name though. It had like 3 or 4 words to it.
