Give the command
format long g
and then display the result again.
By default, MATLAB only displays 4 decimal places, but the values are stored internally to higher precision.

Hint: You might look here:
Knowing that the integral of the Normal density function from -infinity to +infinity is 1 exactly, maybe you can come up with a change of integration variable to get that equation in a form that matches your integral to get the exact answer directly. Starting with a standard Normal density function (mu=0, sigma=1), it is a pretty easy substitution from there to get what you have.
