This is an integral with a spike that is not in the middle of the integral range. Here is the integral... NIntegrate[Exp[-x^2], {x, -900, 1000}] Mathemtaica 5.2.2 gives this error message.... "Numerical \integration stopping due to loss of precision. Achieved neither the requested \PrecisionGoal nor AccuracyGoal; suspect one of the following: highly \oscillatory integrand or the true value of the integral is 0. If your \integrand is oscillatory on a (semi-)infinite interval try using the option \Method->Oscillatory in NIntegrate. More? However, to use the option "Method->Oscillatory" one of the bounds of the integral must be infinity, so that would not work here. How do I get it to to the integral in the range -900 to 1000?? The correct answer is 1.77245.
