Nope, the results are the same, it's just the notation that has
changed over time. I did send in a patch but it didn't make it
in the latest release.
4.0000000e-02 just means 4 times 10 to the power -2 which is
4 times 0.01 which is 0.04
For people not used to scientific notation:
Just shift the decimal point when you see numbers like this.
For negative numbers go left, for positive numbers go right.
4.0e-02 means 0.04 (decimal point is shifted left by two)
4.0e-01 means 0.4 (decimal point is shifted left by one)
4.0e+00 means 4 (decimal point is not shifted)
4.0e+01 means 40 (decimal point is shifted right by one)
4.0e+02 means 400 (decimal point is shifted right by two)
etcetera.
