Dear all, I am happy to accept that > is.integer(1) [1] FALSE
But I'm having difficulty with this one: > as.integer((2.53-2)*100) [1] 52 especially since: > as.integer((1.53-1)*100) [1] 53 Although I know that this is a precision issue since > x <- (2.53-2)*100 > x-53 [1] -2.131628e-14 And I can always use the round function to get what I want, but I just wonder if something is wrong here. > sessionInfo() R version 2.13.1 (2011-07-08) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=Thai_Thailand.874 LC_CTYPE=Thai_Thailand.874 LC_MONETARY=Thai_Thailand.874 [4] LC_NUMERIC=C LC_TIME=Thai_Thailand.874 attached base packages: [1] stats graphics grDevices utils datasets methods base Thanks, Edward -------------------------------------------------------------------------------------------------------------- NOTE: Prince of Songkla University will NEVER ask for your PSU Passport/Email Username or password by e-mail.
