I got these P.values:
1.0e-112 *
0.0000 0.0000 0.0000 0.1819
Even with format short, I see this : 1.0e-112 *
What does it mean?

1.0e-112 is 100 septrigintillionths or or 0.0000.....1 where there are 111 zeros to the right of the decimal place.
Multiply that value by the vector of p values to get calculated p value.
1.0e-112 * 0.1819
Now it's 0.000........1819 with 112 0s to the right of the decimal before the ending.
In other words, the p value would be considered "highly significant" and you can reject the null hypothesis.
