Re: [R] RV: R question
which is the maximum large of digits that R has?, because SQL work with 50 digits I think. and I need a software that work with a lot of digits. The .Machine() command will provide some insight into these matters. cu Philipp -- Dr. Philipp Pagel Lehrstuhl für Genomorientierte Bioinformatik Technische Universität München Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/ __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

I am wondering if that is binary or decimal. and I need a software that work with a lot of digits. The .Machine() command will provide some insight into these matters. On my device (and I suspect on all versions of R) .Machine is a built- in list and there is no .Machine() function. .Machine returns a list that includes $integer.max [1] 2147483647 And you can look at the FAQ: http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-doesn_0027t-R-think-these-numbers-are-equal_003f Which tells you that R can handle 53 digits _binary_ In agreement with these components of .Machine: $double.base [1] 2 $double.digits [1] 53 ... and the FAQ has some explicit warnings about trusting more than 16 digits decimal. And look at the package, 'gmp'. cu Philipp -- David Winsemius, MD West Hartford, CT __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
