I have encountered a strange behaviour of as.integer() which does not seem correct to me. Sorry if this is just an indication of me not understanding floating point arithmetic.
> .57 * 100 [1] 57 > .29 * 100 [1] 29 So far, so good. But: > as.integer(.57 * 100) [1] 56 > as.integer(.29 * 100) [1] 28 Then again: > all.equal(.57 * 100, as.integer(57)) [1] TRUE > all.equal(.29 * 100, as.integer(29)) [1] TRUE This behaviour is the same in R 2.10.1 (Ubuntu and Windows) and 2.9.2 (Windows), all 32 bit versions. Is this really intended? ______________________________________________ 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.
