Re: [R] Using Rmpfr to round with precision in R

Thanks Martin, looks like the update fixed the issue. The round2 function is just to format the output. now I can get the correct result: library(Rmpfr) sprintf("%#.2f", round(mpfr(1.152, 200),2)) round2(1.152, 2) #[1] "1.15" Artur 2014-11-27 7:10 GMT-02:00 Martin Mae

[R] Using Rmpfr to round with precision in R

I'm trying to use the Rmpfr library with the round() function to apply the round half to even rule and achieve correct results, without errors due the finite precision of float point values. Example of problem: round(1.225,2) #[1] 1.23 So far, this is what I've achieved: library(Rmpfr) x <- c(1
