@DanielFischer That I understand. I don't understand though how can a delta function appear from that expression.

comment How to do this integral.
@DanielFischer Sorry for the lack of information. $k$ and $p$ are real, I've seen this integral in physics (in quantum field theory). What they do if shift $k$ into the complex plane by adding $\epsilon i$ to it so it can be done. I need to know how it can be done in that case. So we can consider that $\Im k>0$. Btw the solution I have is something of the form $a+b$, where $b$ has a $\delta$ function.

comment Creating random numbers matching mean and standard deviation
For some reason, when reading the question I presumed he was asking for a normal distribution. I don't know why...
