Hello,

I dont have the strongest math foundation, so please excuse me if this is a dumb question.

I was integrating the following in Maple:

$\displaystyle \int_0^1 e^{-x^2} dx$

which produced the answer:

$\displaystyle \frac{1}{2} \ erf(1) \ \sqrt{\pi}$

I've read that the erf is the error function but I don't really understand what it is. How can I obtain a 'Real' value for this?
