If I wanted to print the exact value of x, how would I do it?
Sorry if this is a dumb question. I tried Googling for "R" and "exact" or "round" but all I get are articles about how to round.
Thank you in advance!

Globally solution during all the session
options(digits=16)
> x
[1] 1.00042589212565
or locally just for x:
sprintf("%.16f", x)
[1] "1.0004258921256499"
回答2:
print(x, digits=15)
or
format(x, digits=15)
or
sprintf("%.14f", x)
