If i run the factorial(1:200), the largest value is 7.257416e+306, any value above that is "Inf".

1: Does this means the largest value inside R programming is 7.257416e+306.

we can not calculate the value above factorial(170)?

2 but when i run the code ".Machine$double.xmax", the biggest value is 1.797693e+308.

so i am bit confused, which one is the biggest value in R.
