Michael,
The 1/10 in the 1st expression enables an exact evaluation,
while the 0.1 in the 2nd expression forces a numerical evaluation.
Avoid floating point numbers with decimal points if you want an exact
answer.
Cheers,
Dave Snead

Greetings!
I found that evaluation of this 2 integrals yield a bit different result.
What could be the reason?
Integrate[E^(-1/10 ((1 + r2z)^2)), {r2z, -Infinity, Infinity}]
Integrate[E^(-0.1 ((1 + r2z)^2)), {r2z, -Infinity, Infinity}]
