Isn't it true that 0 < 2.2e-16?

Dear all
How does print.htest display the p-value in scientific notation?
(x<- cor.test(iris[[1]], iris[[3]]))
Pearson's product-moment correlation
data: iris[[1]] and iris[[3]]
t = 21.65, df = 148, p-value< 2.2e-16
alternative hypothesis: true correlation is not equal to 0
95 percent confidence interval:
0.8270 0.9055
sample estimates:
cor
0.8718
Above the p-value comes as '< 2.2e-16', while inspecting the object I
get a good old '0'.
x$p.value
[1] 0
I tried to inspect print.htest but couldn't find it. I also played
with format, round and the like to no avail. Any pointers?

Liviu
