Enter an arbitrary-precision number with 10-digit precision and a similar number with 10-digit accuracy: Specifying that x has precision 10 implies a certain value for its accuracy, which in this case is less than 10. The gmp and rcdd packages deal with multiple precision arithmetic (via an interace to the gmp library), but this is mostly related to big integers rather than more decimal places for your doubles. While its default setting is to show 2 decimal places (e.g., 3.00) at all times, all it takes is a few button pushes to adjust the decimal place setting. I was able to roughly solve my problem using rational numbers & prime factorization, but this is very compute expensive. Garage door suddenly really heavy, opener gives up. Or see how GMP does it?

This approach increases the number of digits output but doesn't actually affect the accuracy of the floating point calculation. As to the second question, since R uses finite precision arithmetic, your answers aren't accurate beyond 15 or 16 decimal places, so in general, more aren't required. prints with approximate real numbers having n digits, with f digits to the right of the decimal point.
