How can I get R to change the default precision value? For example:
x=0.99999999999999999
1-x
[1] 0
Is there a way that I can get a non-zero value using some parameter, or some
package?
many thanks.
The 'gmp' package allows calculation with arbitrary precision rationals
(and every finite-digit decimal is a rational).
See a recent post of mine, listing some gmp examples:
