Finding value of z-score.

How do I find the corresponding value to a certain z-score? Besides using the table of value.

I was assuming that if $z>0$ then I need to compute:
$\frac{1}{ \sqrt{\pi} } \int_0^z e^{-x^2} dx$
But that does not work when I numerically integrate that.

$\frac{1}{ \sqrt{2 \pi} } \int_0^z e^{-x^2/2} dx$
