p value in excel and R

hi im trying to do t test on rmarkdown and the exponent on both are different, but the rest of the values are the same. is that a significant error?

The two values do not contradict each other: 2e-55 < 2.2e-16. R truncates the level of arbitrary precision shown. The values are effectively zero.

oh i see, this is noted. thank you!
