If here e is Euler then it is 2.718... but it couldn't be, the number being smaller every rows.

In this case, the "$e$" in $2.45225747946181e-07$ indicates that the number coming immediately afterwards is the number of powers of $10$ that you would multiply $2.45225747946181$ by to get the number. So for example, $$2.45225747946181e-07 = 2.45225747946181 \cdot 10^{-07} = 0.000000245225747946181$$ $$2.45225747946181e-05 = 2.45225747946181 \cdot 10^{-05} = 0.0000245225747946181$$ $$2.45225747946181e-01 = 2.45225747946181 \cdot 10^{-01} = 0.245225747946181$$ $$2.45225747946181e 03 = 2.45225747946181 \cdot 10^{3} = 2452.25747946181$$ In this particular case, it has nothing to do with Euler's Constant.
