I ran TukeyHSD test on a linear model which gives me a result with some p-value = 0.00e+00. Does this mean the p-value is very small hence it's significant? or there's error?
diff lwr upr p adj
-12.69650 -18.37280 -7.020199 4.74e-05
44.90700 39.23070 50.583305 0.00e+00
0.00e+00= $0.00...\times 10^0 = 0.00.... \times 1 = 0.00.... \approx 0$ $\endgroup$
