Hi, I would like to increase the Precision of R by
increasing the Number of decimal places in calcultaions. I get about 7 decimal places and would
like to have over 15. is the a means to inflence this?
R uses double-precision for *all* internal floating point numbers. These are 64 bits, on most machines these days.
If you want to change the *display* of your results, use format() e.g.
pi format(pi, digits=15)
If you find that you're getting rounding error in your calculations when using R, check your calculation or algorithm, and see if there's a more numerically stable way to do it.
