Hi,
I want to use a more accurate value of exp(1). The value given by R is
2.718282. I want a value which has more than 15 decimal places. Can anyone let
me know how can I increase the accuracy level.
Actually there are some large multipliers of exp(1) in my whole expression, and
I want a

Where the value of exp(1) as computed by R is concerned, you have
been deceived by what R displays (prints) on screen. The default
is to display any number to 7 digits of accuracy, but that is not
the accuracy of the number held internally by R:
exp(1)
# [1] 2.718282
exp(1) - 2.718282

Well, not really. That is what is printed at the console with the
default settings for digits. The internal representation is wider:

The value in R is accurate to approximately 15
